摘要
以双氧水(H_2O_2)为催化剂,采用高效液相色谱(HPLC)研究了H_2O_2的浓度、溶液初始p H值、降解时间以及不同光源等因素对降解吡虫啉(IMI)农药废水的影响,并对降解条件进行了优化。结果表明,在p H值为中性、光照为紫外光时,随着催化剂用量增多以及降解时间的延长,H_2O_2对IMI的降解效率逐渐增大;在最佳条件下,对实际水样中IMI的降解率均在99%以上。
The hydrogen peroxide（ H_2O_2） was used as catalyst. The influence of H_2O_2 concentration,initial p H value,degradation time and different light were chose on the degradation of imidacloprid（ IMI） pesticide by high performance liquid chromatography（ HPLC）. The degradation conditions were also optimized. The results showed that at neutral p H condition and ultraviolet light,with the increase in dosage of catalyst and the prolongation of the degradation time,the degradation efficiency increased. On optimal conditions,the degradation rate of IMI in real water samples were above 99%.
