Ni_2O_3-CuO对LAS氧化降解的催化作用

Oxidative Degradation of LAS with Catalyst Ni 2O 3 CuO

采用混合催化剂Ｎｉ２Ｏ３－ＣｕＯ和氧化剂Ｈ２Ｏ２对水中ＬＡＳ进行了催化氧化降解实验，研究了氧化剂加量、溶液ｐＨ值、温度等对催化氧化ＬＡＳ的影响，通过正交实验及结果分析，确定了最佳反应条件和显著性影响因素。在最佳反应条件下，水中ＬＡＳ的去除率达到了９９．５％，出水成分主要是碳酸盐和硫酸盐等无机盐类。

The experiments of catalytic oxidation that removed LAS with catalyst Ni 2O 3 CuO and oxidate H 2O 2 in water have been made.The effect of the amount of oxidate,pH values,temperature in water has been studied.Based on orthogonal experiment and experimental data,the optimum reaction conditions and the key factors have been discussed.The removal rate of LAS was reached 99 5% under the optimum reactive conditions.The major compositions of product were carbonate and sulphate.
