The microwave and HCl were used to modify zeolite,Single factor experiments were conducted and on this basis optimization experiments were conducted. The optimization methods were as follows: the HCl concentration of1. 5 mol / L,microwave power of 640 W,and radiation time of 6 min. The performances and the adsorption kinetics of adsorbing Zn2 +in waste water by the modified zeolite were investigated. The results showed that under the conditions of p H = 7. 0,normal temperature,adsorption time 75 min and dos...
