Abstract

The application of sulfur and nitrogen co-doped carbon quantum dot−potassium permanganate chemiluminescence (CL) system for the determination of trace amounts of deltamethrin insecticide was investigated. The results showed that traces of deltamethrin significantly increased the CL of this system in the optimized conditions. This increase was proportional to the concentration of deltamethrin and was used for its determination. We prepared sulfur and nitrogen co-doped carbon quantum dots by hydrothermal method and characterized by fluorescence, X-ray and infrared spectra and transmission electron microscopy. In the optimum analytical conditions, the calibration graph was linear in the range of 1.8 to 20.0 µg/L with a detection limit of 0.3 µg/L. The new tested method has simple set up, high sensitivity and has been successfully applied to the determination of deltamethrin in water samples.

使用硫氮共掺杂碳量子点作为化学发光探针测定水样中的溴氰菊酯

摘要

硫氮共掺杂碳量子点-高锰酸钾化学发光（CL）的应用) 研究了测定痕量溴氰菊酯杀虫剂的系统。结果表明，在优化条件下，痕量溴氰菊酯显着提高了该系统的 CL。这种增加与溴氰菊酯的浓度成正比，并用于其测定。我们通过水热法制备了硫和氮共掺杂的碳量子点，并通过荧光、X 射线和红外光谱以及透射电子显微镜对其进行了表征。在最佳分析条件下，校准图在 1.8 至 20.0 µg/L 范围内呈线性，检测限为 0.3 µg/L。新测试方法设置简单，灵敏度高，已成功应用于水样中溴氰菊酯的测定。
