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。
In this experiment, the hydroxyl radical generator was used to treat the aqueous solution to be tested with pesticide standards. The relationship between the conductivity of the aqueous solution, the generator power, the initial concentration of pesticides, the degradation time and the degradation rate of pesticides was studied. The results showed that the degradation rate of pesticides was positively correlated with the conductivity, degradation time and generator power of aqueous solution, and negatively correlated with the initial pesticide concentration. This study opens up new ways for pesticide degradation in water.
