摘要
本文提出了简便、快速的岩矿中磷、砷联测方法。采用硫代硫酸钠还原掩蔽正砷酸,铋钼蓝分光光度法联合测定岩矿中磷、砷量,该方法准确高,重现性好。
A simple and rapid method for simultaneous determination of phosphorus and arsenic in mineral is presented.Both phosphorus and arsenic are tested in bismuthmolybdate blue system using sodium thiosulfate as a mask reagent of arsenic acid.The method proved the high accuracy and good repetition.
