Sodium peroxide is used to melt and acidate samples and then with the same liquor, the ammonium persulfate oxidation volumetric method, molybdenum blue photometric method and ammonium persulfate argento-oxidation photometric method are respectively used to determine Cr, P and Mn. 用过氧化钠熔融酸化的方法处理样品,用同一母液分别以过硫酸铵氧化容量法测定铬、钼蓝光度法测定磷,过硫酸铵银盐氧化光度法测定锰。
