摘要：

The cation-exchange capacity (cec) and the pore size of zeolite materials are the two key factors which influence the removal of calcium and magnesium in aqueous solution. Na-X and Na-Y zeolites have been modified by selective extraction of Si from the zeolite framework using sodium carbonate. At ambient temperature, the modified Na-X zeolite was more efficient than the Na-A commercially used in detergency, for both Ca and Mg ions.
