摘要
研究活性炭对水溶液中重金属离子铅的吸附行为。废水pH值为5.0～6.0,铅离子质量浓度为100mg/L,按铅与活性炭质量比为1:400投加活性炭,吸附接触时间80min,铅离子去除率可达99%。吸附符合Freundlich等温模式和Langmuir等温模式。穿透体积40mL,活性炭吸附铅离子饱和吸附容量为54.96mg/g。
The adsorption behaviors of activated carbon for the heavy metals lead are studied.The results show：when pH of lead-containing wastewater is 5.0～6.0,lead mass concentration is 100mg/L,the ratio of lead and activated carbon is 1：400,the contacting time is 80 min,the removal rate of lead could be 99%;the adsorption is accord with Freundlich adsorption isotherms and Langmuir adsorption isotherms;the volume of penetration is 40 mL,the adsorption capacity of activated carbon for lead is 54.96mg/g.
