Abstract:

The catalysis of ZnO/Ni₂O₃ on the oxidizing treatment of Linear Alkylbenzene Sulfonate (LAS) in aqueous solution was studied. Various factors which affect LAS removal efficencies were analyzed. Based on orthogonal experiments and experimental data anslysis ,the optimum reaction conditions have been determined. The results showed the average removal rate of LAS was 9₃.8% under the conditions that the NaClO was 0.1 mL/L, ZnO/Ni₂O₃ was 1.5 g/L, pH values was 4.

Key words: LAS, catalytic oxidation, catalyst

摘要：

研究了催化剂ZnO/Ni₂O₃对水中十二烷基苯磺酸钠（LAS）氧化降解的催化作用，并对影响催化氧化反应的因素进行了探讨，通过正交实验确定了最佳反应条件。实验表明：对浓度为₂0mg/L的LAS溶液，在氧化剂NaClO加量为01mL/L、催化剂加量15g/L、pH值为4时，经₂h催化氧化反应，其平均去除率达9₃8%.
