Abstract

In this study, the residue of toxic 2-mercaptobenzothiazole, a semi-volatile heteroaromatic, was extracted from wastewater using a new spectrofluorometric method. The method is based on measuring 2-Mercaptobenzothiazole the quenching effect on the fluorescence intensity of ZnS quantum dot–gelatin nanocomposite in (pH 4, λ_ex 310 and λ_em 345 nm, in time 60 s). Different factors affecting the reaction were studied and optimized. The calibration plot is linear in the concentration range of (0.05–10.0 µgL⁻¹). The relative standard deviations and the detection limit of the method were ±1.0% and 0.05 μgL⁻¹, respectively. Observed, outcomes confirmed the suitability recovery and a meager detection limit for analyzing toxic 2-Mercaptobenzothiazole in water samples. The preliminary results from this study demonstrate that this new method can be used to analyze 2-mercaptobenzothiazole in wastewater.

利用 ZnS QDs-明胶纳米复合材料设计一种荧光方法，用于检测水样中的有毒 2-巯基苯并噻唑

本研究采用一种新的光谱荧光法从废水中提取了有毒的2-巯基苯并噻唑（一种半挥发性杂芳烃）残留物。该方法基于测量 2-巯基苯并噻唑对 ZnS 量子点-明胶纳米复合材料荧光强度的淬灭效应（pH 4，λex 310 和 λem 345 nm，时间 60 s）。对影响反应的不同因素进行了研究和优化。校准图在浓度范围（0.05-10.0 µgL-1）内呈线性关系。方法的相对标准偏差和检测限分别为 ±1.0% 和 0.05 μgL-1。观察结果证实，该方法适用于分析水样中有毒的 2-巯基苯并噻唑，且检出限较低。这项研究的初步结果表明，这种新方法可用于分析废水中的 2-巯基苯并噻唑。

期刊介绍： The Journal of Sulfur Chemistry is an international journal for the dissemination of scientific results in the rapidly expanding realm of sulfur chemistry. The journal publishes high quality reviews, full papers and communications in the following areas: organic and inorganic chemistry, industrial chemistry, materials and polymer chemistry, biological chemistry and interdisciplinary studies directly related to sulfur science. Papers outlining theoretical, physical, mechanistic or synthetic studies pertaining to sulfur chemistry are welcome. Hence the target audience is made up of academic and industrial chemists with peripheral or focused interests in sulfur chemistry. Manuscripts that truly define the aims of the journal include, but are not limited to, those that offer: a) innovative use of sulfur reagents; b) new synthetic approaches to sulfur-containing biomolecules, materials or organic and organometallic compounds; c) theoretical and physical studies that facilitate the understanding of sulfur structure, bonding or reactivity; d) catalytic, selective, synthetically useful or noteworthy transformations of sulfur containing molecules; e) industrial applications of sulfur chemistry; f) unique sulfur atom or molecule involvement in interfacial phenomena; g) descriptions of solid phase or combinatorial methods involving sulfur containing substrates. Submissions pertaining to related atoms such as selenium and tellurium are also welcome. Articles offering routine heterocycle formation through established reactions of sulfur containing substrates are outside the scope of the journal.
