摘要
通过等温吸附试验 ,研究了钙基膨润土及钠化改性膨润土对Cd2 +的吸附 ,并与土壤对Cd2 +的吸附进行了对比 .试验表明 ,钠化改性膨润土对Cd2 +有很好的吸附作用 ,可用于重金属污染土壤的治理 .pH值是影响吸附效果的一个重要因素 .
The adsortion of cadmium ions in Ca-bentonite and Na-modified bentonite was studied by isothermal adsorption method.Those results were compared with the adsorption of cadmium ions in soil,and shown that Na-modified bentonite has a high affinity for cadmium ions,it can be used to remedy heavy metal contaminated soils.pH value is an important factor to for affecting adsorption.
