摘要
氯碱工业中 ,电解食盐水用的金属阳极 ,表面上有含 Ru O2 的活性涂层。钌是贵重金属 ,从旧电极上与阳极泥中回收钌有重要价值。该文介绍了从旧电极表面剥落钌的方法 ,以及从剥落液中和阳极泥中回收钌的方法 ,该方法的回收率达 95%以上。
In chloric alkali industry,when we electrolyze sodium chloride solution,an active coat contained RuO 2 is deposited on the facies of the dimensionally stabe anode.As a kind of precious metal,reclaiming Ru from anodic mud is of great value.This article briefs how to desquamate Ru from the surface of obsolete electrode and then how to reclaim Ru from the liquor and anodic mud.The efficiency of this method can attain to 95%.
