摘要
研究了活性炭纤维电极经ZnCl_2改性前后对Mg~(2+)的电吸附性能,考察了初始溶液浓度、电极电压、电极间距等因素对电吸附行为的影响规律。实验结果表明:ZnCl_2改性可以提高活性炭纤维电极的电吸附速率和电吸附容量。电吸附过程中,吸附速率、吸附量及除盐率均随初始溶液浓度的、电压的增大而增大。在电极电压为1.8 V,极距为6 mm,经ZnCl_2改性后电极对初始溶液浓度为100 mg/L的氯化镁溶液除盐率可达到80.8%。
The adsorption performance of activated carbon fiber electrode modified by ZnCl_2 in MgCl_2 solutions was studied.The influences of concentration of solutions and voltage were investigated.The results showed that after modified by ZnCl_2,the adsorption rate and adsorption capacity of electrode enhanced.The adsorption rate,electrosorption capacity and removing rate increased with the initial concentration and voltage increased.When the voltage was 1.8 V,electrode distance was 6 mm,and initial concentration of solution 100 mg/L,the removing rate of Mg~(2+) could be up to 80.8%.
