摘要
利用Fe2+、Mn2+和腐殖酸对水中甲草胺进行了催化臭氧化研究.实验表明,少量的催化剂就可促进甲草胺的降解,过量则会产生抑制作用.深入研究表明,甲草胺的降解与具有极强氧化能力的羟基自由基有关.
Applying Mn2+, Fe2+ and humic acid for catalytic ozonation of alachlor in water was studied. The degradation of alachlor could be promoted with a small amount of catalyst and the restrain action could be produced with excessive catalyst. Alachlor degradation was related with the hydroxyl free radical of very strong oxidizing ability.
