以废弃花生壳和小麦秸秆为原料,对模拟废水进行了Cd2＋吸附试验研究.结果表明,溶液pH值、溶液温度、Cd2＋初始质量浓度、花生壳粉和秸秆粉的用量、吸附时间等因素均对吸附效果有一定影响.在Cd2＋初始质量浓度为25mg/L、pH值为6、吸附剂投加量0.25g、恒温振荡120min的条件下,花生壳粉和小麦秸秆粉对Cd2＋的去除率分别为63.2%和52.4%.

This paper carries out experimental study on removing Cd2+ from simulated waste water with peanut shell and wheat straw. The results show that factors such as pH value and temperature of solu- tion, initial concentration of Cd2+ , quantities of peanut shell and wheat straw, as well as adsorption time have some effects on adsorption results. Under condition as initial Cd2+ concentration of 25 mg/L, pH value of 6, adsorbent dosage of 0. 25 g and stability temperature oscillated for 120 min, removal rate of Cd2+ with peanut shell and wheat straw is 63.2% and 52.4%.
