The cutting saw blade with diamond blade and carbon steel matrix is widely used in stone cutting because of its high strength, impact resistance and good thermal stability. However, the carbon steel matrix is easy to corrode in the circulating cooling water, which shortens its service life. In this study, a new highly efficient benzotriazole-based (BMN) composite inhibitor was synthesized and investigated against the corrosion of carbon steel in stone processing wastewater. The corro- sion inhibition properties and mechanism of prepared BMN for carbon steel in real stone processing wastewater were evaluated and deduced using the experimental weight loss, electrochemical and surface morphology characterization techniques. Weight loss methods results showed that a high inhibition efficiency of 99.59% in stone processing wastewater was achieved at ambient temperature, with the stirring speed 200 rpm, the immersion time 7 d, and the BMN concentration is 50 mL·L –1 . Electrochemical impedance spectroscopy indicated that resistance from the surface films ( R 2 ) and charge transfer resistance ( R 3 ) were enhanced with increase in BMN concentration. Polarisation results revealed the BMN acted as an anodic inhibitor, owing to the addition of BMN resulted in the significant change of anodic Tafel slopes ( β a ). Scanning electron microscopy results indicated BMN formed a protective film on the surface of carbon steel through adsorption. In short, the prepared BMN composite inhibitor exhibited superior anti-corrosion performance for saw blade corrosion in stone processing wastewater, which had great application potential in industries.

This work investigates the adsorption and the photocatalytic degradation performance of dyes (methylene blue (MB) and methyl orange (MO)) on the surface of raw bentonite (Raw-B) and doped bentonite with titanium oxide (TiO 2 -B). The bentonite was selected from the Nador region in north- ern Morocco, it was doped with various TiO 2 mass ratios. The structural, mineralogical and mor- phological composition of Raw-B and TiO 2 -B was characterized using several techniques including inductively coupled plasma atomic emission spectroscopy, X-ray diffraction, Fourier-transform infrared, transmission electron microscopy, and energy-dispersive X-ray analysis. The adsorption process of MB and MO were affected according to the Langmuir and Freundlich isotherms. The maximum removal capacity of MB and MO were around 60.97 and 142.85 mg/g, respectively. MB and MO degression ratios achieved 100% under a lamp irradiation at 245 nm. The results obtained show that the application of titanium oxide-doped bentonite has a very high performance in wastewater treatment.

In this study, a potato wastes based magnetic carbon nanocomposite (PMCNC) was synthesized and explored for its possible applications as adsorbent in removal of lambda-cyhalothrin from synthetically contaminated water. The nanocomposites were characterized through energy-dispersive X-ray, X-ray diffraction analysis, scanning electron microscopy, Fourier-transform infrared spectrophotometry, zero-point charge (pH pzc ) and thermogravimetric/differential thermal analysis. For the demonstration of adsorption efficiency of the nanocomposite, batch adsorption experiments were carried out. Maximum removal of selected pollutant was achieved in 30 min. Several kinetic and isotherm models were applied to the sorption kinetics and isothermal data. The pseudo-sec-ond-order kinetics fitted well the data. The X max (maximum adsorption) at 50°C was recorded as 14.025 mg/g with K 2 (pseudo-second-order kinetics constant) value of 0.0162 and R 2 value of 0.99. The adsorption isotherm data fitted well the Langmuir isotherm model. The optimum pH for the removal of lambda-cyhalothrin was achieved at pH 5. 0.1 g of PMCNC was used as optimum dose in all experiments. The negative value of Gibbs free energy reveals that the removal of lambda-cyhalo-thrin is a spontaneous process. Due to the excellent adsorption capability and easy separation from slurry after use through the application of magnet the PMCNC can be effectively used as an effective sorbent alternative to activated carbon for the removal of inorganic and organic contaminants from aquatic media. This nanocomposite could compete with other adsorbents in the field of surface chemistry warranting further experimentation.
本研究合成了一种马铃薯废物基磁性碳纳米复合材料(PMCNC)，并探索了其作为吸附剂去除合成污染水中的高效氯氟氰菊酯的可能性。通过能量色散x射线、x射线衍射分析、扫描电镜、傅里叶变换红外分光光度计、零点电荷(pH pzc)和热重/差热分析对纳米复合材料进行了表征。为了验证纳米复合材料的吸附效率，进行了批量吸附实验。选定污染物的最大去除在30分钟内实现。几种动力学和等温模型应用于吸附动力学和等温数据。拟二、二阶动力学与数据拟合较好。50℃时最大吸附量为14.025 mg/g，准二级动力学常数k2为0.0162,r2为0.99。吸附等温线数据与Langmuir等温线模型拟合良好。pH为5时，氯氟氰菊酯脱除效果最佳。所有实验均以0.1 g PMCNC为最佳剂量。吉布斯自由能为负值，表明氯氰菊酯的去除是一个自发过程。由于优异的吸附能力和使用后易于从浆料中分离，通过磁铁的应用，PMCNC可以有效地用作活性炭的有效吸附剂，用于去除水生介质中的无机和有机污染物。这种纳米复合材料可以在表面化学领域与其他吸附剂竞争，需要进一步的实验。
