摘要
采用振荡平衡法，研究了4种不同粒径竹炭对水中Pb^2＋的去除效果以及不同环境因素对去除率的影响。结果表明，Pb^2＋在竹炭上的吸附符合Freundlich和Langmuir方程；竹炭对Pb^2＋有很强的吸附能力，竹炭粒径越小，对Pb^2＋的吸附能力越强；吸附时间为4h、pH6.0-7.0、温度25℃、竹炭用量10mg／L为最佳去除条件。
The removal rates of Pb^2＋ from water by four different particle sizes of bamboo-charcoals and the influence factors were studied using batch equilibration technique. The adsorption data of Pb^2＋ on the bamboo-charcoals fitted the Freundlich and Lang-muir empirical equation. The results showed that bamboo-charcoal had a great adsorption capacity for Pb^2＋, and the smaller the particle size of bamboo-charcoal, the more the adsorption of Pb^2＋. The optimization condition of removing Pb^2＋ from water are as follows： equlibrium time four hours, pH6-7, 25℃ and 10mg/L of bamboo-charcoal.
