摘要

随着纳米氧化锌产量的不断增加及其在卫生产品中的应用，从公共健康和环境风险的角度来看，对其进行分析和定性极为重要。这项工作旨在验证使用 SP-ICP-MS 测量和定量纳米氧化锌颗粒和溶解锌（i）的方法。研究结果表明，该方法适用于这一目的，在锌(i)的回收率和精密度以及纳米粒子的大小方面都取得了令人满意的结果。该方法的检出限、溶解锌浓度和颗粒浓度分别为 67 nm、0.4 µg L-1 和 1.08 × 105 mL-1。因此，所得结果表明该技术可用于测定不同产品中锌(i)的大小和浓度。

Development of the methodology for the detection and quantification of zinc oxide nanoparticles and dissolved zinc by single-particle inductively coupled plasma mass spectrometry

The increasing production of zinc oxide nanoparticles and their use in products of sanitary interest make the analysis and characterization extremely important from the point of view of public health and environmental risk. This work aimed to validate the methodology using SP-ICP-MS to measure and quantify nanoparticles of ZnONPs and dissolved zinc—Zn(i). This study pointed out that the method was suitable for the purpose, presenting satisfactory results for the recovery and precision test for Zn(i) and size of NPs. The limits of detection size, dissolved zinc concentration, and particle concentration were 67 nm, 0.4 µg L⁻¹, and 1.08 × 10⁵ particles mL⁻¹, respectively. Thus, the results obtained demonstrate that the technique can be used to determine the size and concentration of Zn(i) in different products.

期刊介绍： The objective of the Journal of Nanoparticle Research is to disseminate knowledge of the physical, chemical and biological phenomena and processes in structures that have at least one lengthscale ranging from molecular to approximately 100 nm (or submicron in some situations), and exhibit improved and novel properties that are a direct result of their small size. Nanoparticle research is a key component of nanoscience, nanoengineering and nanotechnology. The focus of the Journal is on the specific concepts, properties, phenomena, and processes related to particles, tubes, layers, macromolecules, clusters and other finite structures of the nanoscale size range. Synthesis, assembly, transport, reactivity, and stability of such structures are considered. Development of in-situ and ex-situ instrumentation for characterization of nanoparticles and their interfaces should be based on new principles for probing properties and phenomena not well understood at the nanometer scale. Modeling and simulation may include atom-based quantum mechanics; molecular dynamics; single-particle, multi-body and continuum based models; fractals; other methods suitable for modeling particle synthesis, assembling and interaction processes. Realization and application of systems, structures and devices with novel functions obtained via precursor nanoparticles is emphasized. Approaches may include gas-, liquid-, solid-, and vacuum-based processes, size reduction, chemical- and bio-self assembly. Contributions include utilization of nanoparticle systems for enhancing a phenomenon or process and particle assembling into hierarchical structures, as well as formulation and the administration of drugs. Synergistic approaches originating from different disciplines and technologies, and interaction between the research providers and users in this field, are encouraged.
