Determination of Deltamethrin in Water Samples Using Sulfur and Nitrogen Co-Doped Carbon Quantum Dots as a Chemiluminescence Probe

Determination of Deltamethrin in Water Samples Using Sulfur and Nitrogen Co-Doped Carbon Quantum... 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. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Analytical Chemistry Springer Journals

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.
