摘　　要：研究了高价铈的绿色还原剂及其工艺参数。分别以醇、酮、酯、酸和胺作绿色还原剂,在酸性溶液中与Ce( )反应生成H2O和CO2,对温度、酸度及反应时间等进行了优化实验研究,确定了最佳工艺参数,Ce( )的还原率最高可达99.70%。同时,对绿色还原工艺做了原子效益、经济效益分析。The green reductants of reducing Ce(Ⅳ) and the process parameters are studied in this paper.In this method,organic reductants are transformed into water and carbon dioxide in the sulfuric acidic solution.The alcohol,ketone,ammonia,ester and acid are studied separately as green reductants.Process parameters under different reaction conditions are investigated and the optimal process parameters are obtained.And then,the atomic profit,economic and environmental benefit are analyzed.
