摘要
采用浸渍法,以硫酸铜溶液对椰壳活性炭进行改性,研究改性剂浓度、浸渍时间和改性温度对成品吸附焦化废水的吸附效果。结果表明,改性后活性炭对焦化废水的吸附效果优于改性前,当298 K下,CuSO4溶液浓度为1 mol/L,改性时间4 h时,改性后活性炭对焦化废水的吸附效果最好,COD去除率为76.86%。
The activated carbon( AC) was modified by copper sulphate. The effects of modification on the adsorption behaviors of coking wastewater onto AC at different concentration,modification timeand temperature were researched. The results show thatthe COD removal efficiency of coking wastewater was enhanced after modified,when 5 g AC was modified by 50 m L CuSO4 in 4 h at298 K,the COD removal efficiency was to reach76. 86%.
