摘要
提出了简便、快速、无毒害的磷、砷联测方法。采用硫代硫酸钠在铋钼蓝体系中还原掩蔽正砷酸而制取参比 ,实现了磷、砷联测。线性范围 0 0 10 %～ 0 70 0 % ,证明该方法准确 。
A simple,rapid and nontoxic method for combintd determination of phosphorus and arsenic is presented.Both phosphorus and arsenic are tested in bismuthmolybdate blue system using sodium thiosulfate as a mask agent of arsenic acid to make reference.The linearity region of 0 010% to 0 700% proved the high accuracy and repetitiveness of test results.
