基于·OH的水中11种农药污染物消解研究

Study on Degradation of 11 kinds of Pesticide Contaminants in Water Based on ·OH

本实验采用羟基自由基发生器处理添加有农药标准品的待测水溶液,研究了水溶液的电导率、发生器功率、农药初始浓度、降解时间与农药降解率的关系。结果表明,农药降解率与水溶液电导率、降解时间、发生器功率呈正相关性,与农药初始浓度呈负相关性。本研究为水中农药降解技术开辟了新的途径。

Hydroxyl radical （,OH） generator was used to study the degradation rate of 11 pesticide standards spiked in the aqueous solution on the effects of the pesticide treated with electrical conductivity of the aqueous solution, generator power, initial concentration and degradation time. The result showed that the degradation rate was positively correlated to the electrical conductivity of water, degradation time and the generator power, but negatively correlated to initial concentration. Therefore, this study would carve out a new way for pesticide degradation in water.
