Abstract以合成的Friedel盐（FS,3CaO·A12O3·CaCl2·10H2O）为吸附剂,研究了FS去除废水中Cd2＋的反应动力学和等温吸附特性.考察了FS盐用量、温度及Cd2＋初始浓度对Cd2＋去除的影响.结果表明,FS用量为0.03g/L时,在室温下对废水中初始浓度为10mg/L的Cd2＋的去除率大于94.34%,吸附容量可达301.9mg/g,吸附主要以离子交换吸附为主,最终形成Cd4Al2（OH）12Cl2（H2O）4xH2O及Cd4Al2（OH）12Cl24H2O化合物.利用一级动力学模型关联了反应动力学数据,得到速率常数k=0.049min-1,吸附行为较符合Langmuir等温吸附方程.
