摘　　要：以模拟含铅废水为研究对象,实验研究均苯四甲酸二酐改性柚子皮吸附剂对铅离子的去除能力。研究改性柚子皮吸附剂的加入量、粒径大小、吸附时间、pH、温度等因素对废水中铅去除率的影响。结果表明:均苯四甲酸二酐改性柚子皮吸附法处理过的废水中铅的含量为(0.0344±0.0044)mg/L,耗时40 min,铅的去除率为96.56%。Taking simulated lead-containing wastewater as a research object,the removal ability of lead ion by grapefruit peel modified by pyromellitic dianhydride was studied experimentally.The effect of the amount of adsorbent,pH,time,temperature and particle size of adsorbent on the removal rate of lead from wastewater was investigated.The experimental results showed that,the lead content in the wastewater treated by the adsorption process was(0.0344±0.0044)mg/L,the lead removal rate was 96.56%after 40 min adsorption.
