摘要
对沸石分子筛去除水中钙离子的吸附情况进行了系统的研究,考察了温度、pH值、不同粒径等因素对吸附量的影响。结果表明:4A分子筛与13X分子筛对钙离子均具有较好的吸附效果,两种分子筛对钙离子的最大饱和吸附量分别达到51.97和49.30 mg/g。
The adsorption of zeolite molecular sieves to the removal of Ca^2＋ in water is studied systematically,and the effect of the factors such as the reaction temperature,pH,different diameter of particles on the adsorption quantity are also observed.The result shows that the 4A and 13X molecular sieves present better adsorption on Ca^2＋,and the saturated adsorption quantity of the two sieves on Ca^2＋ are 51.97 and 49.30 mg/g respectively,which means that they are feasible in the Ca^2＋ adsorption.
