摘要
采用sol-gel法制备了载钛活性炭,并用于电吸附处理含铬废水。当Cr(Ⅵ)初始浓度为20 mg/L时,载钛活性炭上施加1.2 V的正向电压,电吸附3 h后的处理水水质满足国家排放标准。研究了载钛活性炭电吸附去除Cr(Ⅵ)的影响因素及TiAC的电脱附再生。
Activated carbon modified by titania film (TiAC) was prepared by sol-gel method. When the anode polarization potential on TiAC was 1.2 V and initial concentration of Cr(Ⅵ) was 20 mg/L, after 3 hours electrosorption, the concentrations of Cr(Ⅵ) and total chromium in effluent were lower than national discharge standard. Affecting factors of electrosorption and the electro desorption regeneration of TiAC were also studied.
