| Abstract: | Linear alkylbenzene sulfonate （LAS） is an anionic surfactant widely used;it is toxic and difficult to degradation. The process of 100 mL 50 mg/L linear alkylbenzene sulfonate catalytic oxidation degradation is tested using NiO/activated carbon/H2O2 as catalyst. The results show that LAS degradation can reach 80% and the CODMn decomposition can reach 71.6% under the optimum conditions：the weight of hydrogen peroxide is 4.9 mmol/L, water temperature is 50℃, initial pH value is 3 - 4, and reaction time is 2 h. |
