摘要
采用磷铋钼蓝分光光度法测定电解金属锰中的痕量磷。对w(P)=0.00080%的电解金属锰样品平行测定10次,其相对标准偏差为6.9%,加标回收率为90%～110%。
A method for the determination of trace phosphorus in electrolyzed metal manganese by spectrophotometry with bismuth-phosphoric molybdenum blue is reported in this paper. The recovery of phosphorus in the sample with w(P)=0.000 80% is 90%～110% with precision of 6.9% RSD (n=10). The method has been satisfactorily applied to the determination of trace phosphorus in electrolyzed metal manganese.
