烟嘧磺隆废水的光降解研究

Photodegradation of Nicosulfuron Wastewater

本文主要研究了烟嘧磺隆废水的光降解特性,考察了照射光源、烟嘧磺隆初始浓度、溶液初始p H值等因素对烟嘧磺隆光降解的影响。结果表明,汞灯照射的光解效果优于氙灯照射;汞灯照射下,p H值为7时光解效果最好,并且随着烟嘧磺隆初始浓度的增加,光解的半衰期增大。

This paper studies the optical degradation characteristics of nieosulfuron wastewater investigated irradiation light source, factors nicosulfuron initial concentration, initial pH value on nicosulfuron light degradation. The results showed that the effects of mercury exposure photolysis than xenon light irradiation; under mercury lamp, pH of 7 times the best solution, and with the increase in the initial concentration of nicosulfuron, the half - life Photolysis increases.
