查询词典 cations

At the heavy metal concentration of 3-4ppm, our study on adsorption capacity, adsorption selectivity of montmorillonite, illite and kaolinite to Cu〓、 Pb〓、 Zn〓、 Cd〓、 Cr〓 shows that the adsorption capacity is mainly determined by the capacity of exchangeable cations and the adsorption capacity of the three clay minerals decreases in this sequence: montmorillonite ＞＞ illite＞kaolinite. It is found that clay minerals have obvious adsorption selectivity to various heavy metals. Montmorillonite exhibits a stronger affinity to Cr〓 and Cu〓 while kaolinite and illite sorb Cr〓 and Pb〓 more effectively. At the same heavy metal concentration, adsorption amount of clay minerals to heavy metals increase with increasing pH value of the solution.
