摘要
采用磷钼蓝光度法测定铁矿中磷含量,优化显色条件、采用酒石酸钾钠掩蔽,抗坏血酸还原,使配合物更稳定,分析结果的准确度和精密度满意。
The method for determination of phosphorus in iron ore by molybdenum blue spectrophotometric method was described with op-timal color conditions, using KNaC4H4O6.4H2O masking, ascorbic acid reduction. The complex was more stable, accuracy and precision of the results was satisfactory.
