【摘要】 研究了在二苯基碳酰二肼显色剂中加入硫酸和磷酸对实验室含铬废液中铬量的测定,并选择还原—沉淀—氧化法对实验室含铬废液进行了处理,由制得的产品及其回收率可见该方法起到了环境保护、废物回收及综合利用的目的。更多还原

【Abstract】 The determination of chromium content in waste liquid contained with chromium from laboratory was simplified by adding sulfuric acid and phosphate to carbon acid bis-diphenyl-hydrazine reagent.And selected restore-settling-oxidation method to deal with waste liquid contained with chromium from laboratory.The recovery of the product obtained showed that the method had played a environmental protection,waste recycling and comprehensive utilization purposed.更多还原
