采用铋盐—钼蓝光度法对铁矿石中微量磷进行测定,确定了最佳测定条件。在HNO3介质中,最大吸收波长为690 nm,磷质量浓度在0—1.2 mg/L范围内符合比耳定律。此方法在室温下,显色速度快,产物稳定性好,线性范围宽。将该方法用于铁矿中微量磷的测定,结果令人满意。

Microamount Phosphorus content in ore samples was determined by Bismuth salts-molybdenum blue spectrophotometfic method,and the optimum conditions were finalized.In the medium of HNO3,the maximum adsorption wave length is 690 nm,the mass concentration of phosphorus is 0-1.2 mg/L and conforms to Beer＇s law.Using the method had the advantages of high reactions rate,good stability and wide linearity range.This method could be used to determine microamoun...
