摘　　要：天然沸石经活化后制得的吸附剂对废水中的Ｐｂ２＋有较强的吸附作用．当每升水吸附剂用量为１０ｇ，吸附时间为１２０ｍｉｎ，Ｐｂ２＋的质量浓度为２０７ｍｇ／Ｌ时，其吸附效率可达９９．５％，吸附容量为３２．０３ｍｇ／ｇ，且较好地符合Ｆｒｅｕｎｄｌｉｃｈ吸附等温式ｑ＝５．５６ρ１．８４．By activation treatment,natural zeolite can absorb lead ions in waste water significantly.The result shows that if concentration of Pb 2+ is 207 g/L in wastewater,additional adsorbent is 10 g in 1 L wastewater and reation time is 120 min,the removal efficiency of lead is 99.5%.The adsorbance is 32.03 mg/g.The adsorption process was conformed to Freundlich isothermal line q=5.56ρ 1,84 .
