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 method of dissolving rhodium was introduced. The efficient activation of dissolved rhodium with aluminum as activator was studied. The single factor test was used to investigate the dissolution of rhodium in aqua regia, respectively, and the optimum conditions were rhodium-aluminum mass ratio 1:10, activation temperature 1200 ℃, activation time 80min , Dissolution time 30min; under optimized conditions, rhodium dissolution rate of 99% or more. The activation mechanism of rhodium is discussed.
