| Abstract: | Using HCl to regenerate D001 resin,the influences of desorbent dosage,time and temperature on desorption effect were investigated through the desorption test;meanwhile,the adsorption performance of D001 resin for iron ions at different HCl concentrations was also investigated through the adsorption test.The results showed that,when the temperature was 25 ℃,the desorption of D001 resin that had adopted iron ions(adsorption quantity was 11.729 mg/g) was carried out using the HCl with a mass fraction of 20%,a higher desorption quantity could be obtained in 60 min,the removal rate of iron ions was 86.37%;With the increasing of HCl concentration,the adsorption performance of the resin and the equilibrium adsorption capacity both decreased. |
