摘要
LAS是一类广泛使用的阴离子表面活性剂,具有一定的毒性,且不易降解。文章以CuO/活性炭(AC)为催化剂,H2O2为氧化剂催化氧化降解LAS。结果表明:在H2O2浓度为4.9mmol/L,温度=70℃,pH在5-6,反应时间为2.5h的条件下,LAS降解率67.7%,COD去除率54.1%。
Linear alkylbenzene sulfonate （LAS）is a kind of widely used anionic surfactant. It is toxic, and difficult to be degraded. CuO/activated carbon is used as surfactant and H2O2 as oxidizing agent for the catalytic oxidation of LAS degradation. The results show that LAS degradation rate could reach 67.7% and the COD removal rate could reach 54.1% under optimum conditions： the concentration of hydrogen peroxide is 4.9 mmol/L, water temperature is 70 ℃,pH is between 5 to 6, and reaction time is 2.5 h.
