摘要
对于铁矿石中磷元素的分析，在排除了硅、铬、砷等元素的干扰后，以锑磷钼蓝光度法取代乙酸丁酯萃取－钼蓝光度法进行显色反应，不仅回收率高，而且避免了有机试剂的污染，标准偏差仅为１．００×１０－４。
After eliminating interference of silicon,chromium,corsenic elements,etc,to analyse phosphorus element in iron ore,antimonphospho molybdate blue spectrophotometric method is substitute for butyl acetate extractionmolybdate blue spectrophotometric method to do colour reaction.This method has high recovery ratio,can aviod pollution by organic solvent and its standard deviation is only 10010-4.
