摘　　要：对铂金属废催化剂进行焙烧体系及浸出体系的重点研究。采用HCl/NaClO3溶浸体系提高了铂的浸出率。经过实验,确定了废催化剂焙烧温度1 200℃,浸出液固比6∶1,氢离子浓度6 mol·L^(-1),浸出时间3 h,浸出温度70℃,氧化剂氯酸钠浓度0.06 mol·L^(-1);HCl/NaClO3体系在1 200℃时一次浸出,铂的平均回收率可达到97.06%。The roasting system and leaching system of waste platinum catalyst were studied.HCl/NaClO3 leaching system improved the leaching rate of platinum.The conditions were determined as follows;the roasting temperature 1200℃,the ratio of solid to leaching liquid 6∶1,the concentration of hydrogen ion 6 mol·L^(-1),the leaching time 3 h,the leaching temperature 70℃,the concentration of oxidant sodium chlorate 0.06 mol·L^(-1).The waste platinum catalyst was leached by HCl/NaClO3 system at 1200℃,the average recovery of platinum reached 97.06%.
