The application of weak-base anion-exchange resin for removal the SO42− from the citrate solution to guarantee its good performance for adsorption of SO2 is proposed in this work. The weak-base anion-exchange resin that has prior adsorption towards SO42− compared with citrate, allows the effective removal of such impure anion. We initially chose four kinds of resins, namely D301R, D301G, D370 and D315, to investigate their behavior upon SO42− adsorption and then determined D301R and D315 to give a comprehensive understanding towards their adsorption performance in various condition. Results indicate that D315 possessing better adsorption ability than D301R could be a potential candidate for SO42− removal from the citrate acid solution during the desulphurization process using citric method. The pretreatment of protonation for resins could effectively facilitate their adsorption behavior towards SO42− under the same pH condition. Moreover, we assume that the protonated D315 would meet the practical requirement well given its good performance. [ABSTRACT FROM AUTHOR] |
