| Abstract: |
| Hydrochloric acid and distilled water were selected to regenerate D201 strong basic anion exchange resin (Cl type). The effects of concentration of eluant, elution time, and elution temperature on elution effect were investigated. The results show that iron elution rate is 98% from D201 resin (adsorption saturation content 9.6 mg/mL) under the conditions including temperature of 25 ℃, 2 times volume of resin of 1 mol/L HCl, and 3 volumes of resin of distilled water to follow. |
