巯基修饰的硫化钼量子点及其制备方法以及2,4,6‑三硝基甲苯的检测方法
Abstract:
本发明公开了一种巯基修饰的硫化钼量子点及其制备方法以及2,4,6‑三硝基甲苯的检测方法，其中，该方法包括：1)先将盐酸羟胺、二硫化钼与溶剂混合，接着进行热处理，然后进行离心纯化以制得巯基修饰的硫化钼量子点；2)将所述巯基修饰的硫化钼量子点、含巯基化合物和溶剂进行混合，接着进行接触反应以制得巯基修饰的硫化钼量子点。该方法制得的巯基修饰的硫化钼量子点具有高量子产率、强抗干扰能力，且稳定性良好。另外，该方法制得的巯基修饰的硫化钼量子点对2,4,6‑三硝基甲苯溶液浓度的检测具有良好的选择性。
Abstract(English):

The invention discloses a sulfydryl-modified molybdenum sulfide quantum dot, a preparation method of the sulfydryl-modified molybdenum sulfide quantum dot and a detection method of 2,4,6-trinitrotoluene, wherein the method comprises the following steps of 1, firstly mixing hydroxylamine hydrochloride, molybdenum disulfide and solvents; then, performing heat treatment; next, performing centrifugal purification so as to prepare the sulfydryl-modified molybdenum sulfide quantum dot; (2) mixing the sulfydryl-modified molybdenum sulfide quantum dot, sulfydryl-containing compounds and the solvents; then, performing contact reaction so as to prepare the sulfydryl-modified molybdenum sulfide quantum dot. The sulfydryl-modified molybdenum sulfide quantum dot prepared by the method has the advantages of high quantum yield, strong anti-jamming capability and good stability. In addition, the sulfydryl-modified molybdenum sulfide quantum dot prepared by the method has the good selectivity on the detection of the 2,4,6-trinitrotoluene solution concentration.
