Using HCI 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 HCI 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 rog/g) was carried out using the HC1 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.%通过脱附试验,选用HCl对D001树脂进行再生,考察了脱附剂浓度、脱附时间、脱附温度对树脂脱附效果的影响;通过吸附试验,考察了D001树脂在不同HCl浓度下对铁离子的吸附.试验结果表明,25℃时,质量分数为20%的HCl在对吸附铁离子的D001树脂(吸附量为11.729mg/g)进行脱附,60min时可达到较大的脱附量,脱铁率为86.37%;随着HCl浓度的增大,树脂的吸附性能越来越差,平衡吸附量越来越小.
