摘　　要：介绍了铑的溶解方法,研究了以铝作为活化剂高效活化溶解铑。采用单因素试验法分别考察铑铝质量比、活化时间、活化温度及溶解时间对铑在王水中的溶解状况,获得优化条件为铑铝质量比1∶10,活化温度1 200℃,活化时间80min,溶解时间30min;优化条件下,铑溶解率为99%以上。探讨了铑的活化机制。The methods for dissolving rhodium were introduced, and using aluminium as activator to high-efficiency activate and dissolve rhodium was studied. Effects of the ratio of aluminum and rhodium mass,activation time, activation temperature and dissolution time on rhodium dissolution in aqua regia were examined. The optimum conditions was determined as follows ： m （Rh）/m （A1） = 1 ： 10,activation temperature 1 200 ℃, activation time 80 min, dissolution time 30 min. Under the optimum conditions,the rhodium dissolution rate is more than 99%. The activation mechanism was also studied.
