摘要
采用４－（－２吡啶偶氮－）－间苯二酚（ＰＡＲ）为显色剂，对钒元素进行吸光光度测定．应用于低合金钢的系统分析中，以实验研究与应用为依据，从吸光光度法的吸收曲线，工作曲线及摩尔吸光系数等几个方面进行了试验．通过研究与应用认为，此法对钒舍量在０．０５％～０．４５％之间的低合金钢都适用，应用于钢的系统分析，简化了分析过程，提高了工作效率．
The article assayed the content. of vanadium by way of absorbance analysis with 4 (2-pyridy- lazo) resorcion as developer to do system analysis on low alloy steel. Base on the experimental research and practical application, tests on absorbance curve, working curve and molar absorptivity etc. were done. We think it suitable to assay low alloy steel with vanadium content ranging from 0. 05% to 0. 45 %. this method also simplifies the process of system analysis on steel and improves the efficiency.
