Design of a fluorescent method by using ZnS QDs-gelatin nanocomposite for sensing toxic 2-mercaptobenzothiazole in water samples
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, λex 310 and λem 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.
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.
