Abstract Total reflection X-ray fluorescence (TXRF) has been widely considered as an effective analytical tool for the analysis of a great variety type of polymetallic deposits, because it has many advantages of extremely high sensitivity, high accuracy, minor sample preparation, and the ability of multielement simultaneous analysis. Sample preparation is quite important for TXRF quantitative analysis. Since pretreatment factors, such as sample amount, dispersant type, sample particle size and sample physicochemical properties, are seriously impact the accuracy of results. Based on this reason, investigating an appropriate sample pretreatment strategy is fundamental for accurate assessment of strategic metal elements in polymetallic deposits. This review presents a comprehensive overview of TXRF applications in the field of mineral analysis, including apatite, manganese ore, K-feldspars, granite, copper-nickel sulfide ore, etc. Moreover, the accurate evaluation of TXRF quantitative analysis is detailedly discussed, and the relevant sample preparation methods and preparation factors are also addressed.

Abstract Corrosion inhibitors are widely employed to retard metal corrosion. Highly sensitive detection and adsorption mechanism analysis are the two important aspects for the systematic research of corrosion inhibitors. Surface-enhanced Raman scattering (SERS) spectroscopy has emerged as a promising tool for the high-resolution detection and inhibition mechanism analysis of corrosion inhibitors in recent decades, and is of considerable importance for their selection and optimization. This paper provides an overview of the SERS technique in the study of corrosion inhibitors adsorbed on noble metals (SERS active substrates) and transition metals (non-SERS active substrates). After surface roughening, the SERS enhancement of metal electrodes can be significantly improved, which intensifies the Raman signals of adsorbed inhibitors to provide sufficient information regarding the binding state and adsorption orientation. In addition to roughening the metal surface to obtain strong SERS signals, novel SERS sensors that can amplify the Raman signals of inhibitors regardless of the type or surface state of the metal substrates are introduced, which is conductive to facilitating the real-time detection of inhibitors. The challenges and future prospects of SERS technique in corrosion inhibitor research are discussed. In summary, SERS technique is expected to promote the research development and engineering applications of corrosion inhibitors.

Abstract Visible–near-infrared–shortwave-infrared (VNIR–SWIR) spectroscopy is one of the most promising sensing techniques to meet ever-growing demands for soil information and data. To ensure the successful application of this technique in the field, efficient methods for tackling detrimental moisture effects on soil spectra are critical. In this paper, mathematical techniques for reducing or removing the effects of soil moisture content (SMC) from spectra are reviewed. The reviewed techniques encompass the most common spectral pre-processing and algorithms, as well as less frequently reported methods including approaches within the remote sensing domain. Examples of studies describing their effectiveness in the search for calibration model improvement are provided. Moreover, the advantages and disadvantages of the different techniques are summarized. Future research including further studies on a wider range of soil types, in-field conditions, and systematic experiments considering several SMC levels to enable the definition of threshold values for the effectiveness of the discussed methods is recommended.

Abstract X-ray fluorescence spectrometry (XRF) has been widely used for multi-element determination in various samples. However, when trace level determination is required, separation and preconcentration procedures are often used as a step before detection to avoid or reduce interferences and to increase sensitivity. Liquid-phase extraction (LPE) is one of the most well-known and applied pretreatment techniques associated with atomic spectrometry due to its simplicity, speed, and ease of automation. A review of methods involving LPE combined with XRF is presented. Methods described in the literature are discussed, involving conventional LPE and the three main categories of liquid-phase microextraction (LPME): single-drop microextraction (SDME), dispersive liquid–liquid microextraction (DLLME), and hollow fiber liquid-phase microextraction (HF-LPME). Characteristics of the methods are presented, considering experimental aspects, analytical features, advantages, and disadvantages. In addition, trends in the association between LPME techniques and XRF are presented.

Abstract Localized surface plasmon resonance (LSPR) sensors using metallic nanoparticles are extensively used for refractive index (RI) measurements in chemical and biological studies, and their sensitivity is highly influenced by the material and structure of the nanoparticle. Despite the great advantages of LSPR sensors using frequency shifts, there are still major challenges in terms of detection sensitivity as well as the broadening and asymmetry of LSPR peaks. This article provides a general background of the fundamentals of LSPR and RI-based LSPR sensing. Thereafter, recent advances in the improvement of LSPR sensitivity are discussed in the viewpoints of two experimental and mathematical approaches. The experimental approaches, including the fabrication of plasmonic array nanostructures with high uniformity and site-selective immobilization, are briefly discussed. Later, we discuss recent studies using a simple mathematical approach with LSPR inflection point to improve the RI sensitivity in gold nanoparticles with different shapes, sizes, shells, etc.

Abstract Hyperspectral imaging is a technique that combines spectroscopy and imaging. Originally utilized in the 1980’s by the remote sensing community it is now utilized in a wide variety of applications. Spectral imaging was first used for the detection of compression wood in the late 1990’s and since that time research focused on wood and wood products has steadily increased with a variety of applications reported. While there are several reviews of wood related research utilizing near infrared spectrometers a comprehensive summary of wood—hyperspectral imaging research is lacking. Near infrared hyperspectral imaging systems (NIR-HSI) typically have a wavelength range of 900–1700 nm, whereas short-wave infrared hyperspectral imaging (SWIR-HSI) systems range from 1000 to 2500 nm. We provide a detailed account of the various studies that have been published utilizing both camera types.

Abstract Volatile organic compounds are a broad and important class of pollutants affecting the indoor air quality. They are emitted from commercial products, building materials, furniture, occupant activities and even occupants, etc., and can participate in the indoor chemistry reacting with oxidants or being formed from secondary reactions. Some VOCs are classified as carcinogens and are associated with a variety of health effects. Characterizing and quantifying the VOCs in the indoor environments is of paramount importance in order to implement preventive measures to minimize the human exposure. A correct assessment of human exposure or characterization of emission sources and indoor activities requires appropriate and efficient methods for sampling and analysis. Therefore, this review focuses on the different methodologies for monitoring VOC that must be selected when a sampling plan is designed considering the objective of the measure. Selecting the most suitable procedures for assessing VOCs requires proper knowledge on the existing standards and off-line (including the selection of the sorbent media) and online instrumentation. Knowing the advantages and drawbacks of the different techniques available can help to plan future studies.

Abstract Radicals and their precursors play a central role in the chemical transformations occurring in indoor air and on indoor surfaces. Such species include OH, HO2, peroxy radicals, nitrous acid, reactive chlorine species, NO3, N2O5, Criegee intermediates, and glyoxal and methylglyoxal. Recent advances on instrumental analysis and modeling studies have demonstrated the need for a wider range of measurements of radical species and their precursors in indoor air. This work reviews measurement techniques and provides considerations for indoor measurements of several radicals and their precursors. Techniques to determine the actinic flux are also presented owing to the relevance of photolytically-initiated processes indoors. This review is also intended to provide pointers for those wanting to learn more about measurements of radicals indoors.

People in developed countries are estimated to spend 80–90% of their time indoors, where they can be exposed to poor air quality from numerous and diverse sources. These include mold growth and other microbial pollutants in humid air, to the chemical pollutants that result from emissions from human activities such as cooking, cleaning, smoking and home refurbishments. In fact, the concentrations of many air pollutants can be higher indoors than out, particularly following activities such as cleaning and cooking. Despite these facts, regulation for air pollution focuses mainly on outdoors and the indoor environment is much less well characterized or indeed regulated. With increasing climate change impacts expected in the future, related energy efficiency measures are making buildings considerably more airtight leading to the potential for even higher indoor air pollutant concentrations. Therefore, to reduce our exposure to air pollution, we must consider air pollutant sources and sinks in both the indoor and outdoor environments. We also need to consider the role of ventilation in mixing air between the two, in order to mitigate through appropriate building operation, use and design. Cost Action 17136 INDAIRPOLLNET (INDoor AIR POLLution NETwork) aims to improve our understanding of the cause of high concentrations of indoor air pollutants. It assembles experts in chemistry, biology, standardization, particulate matter characterization, toxicology, exposure assessment, building materials (including green materials), building physics and engineering and building design, performing laboratory and chamber experiments, modeling studies and measurements of relevance to indoor air quality, including outdoor air chemists. This Action is significantly advancing the field of indoor air pollution science, and highlighting future research areas, as well as aiming to to bridge the gap between research and business. In this way, we will be able to identify appropriate mitigation strategies that optimize indoor air quality. One of the objectives of our Action has been to explore the best ways to measure key indoor air pollutants given specific requirements (research question, available funds, building location and characteristics etc.). This special issue therefore summarizes the various measurement techniques that are currently available for indoor air measurements and the advantages and disadvantages of each for the indoor environment.
