摘要
对硫磺中砷含量的测定方法进行了研究 ,对现行GB2 449-92标准中试样分解方法进行了改进 ,提出用发烟硝酸分解试样 ,用分光光度法测定试样中砷的含量。该法简单、快捷 。
Determination of Arsenium from sulphur was studied,and the decompositron method for the current GB 2449 92 standard was moditied.Samples were decomposed with fuming nitric acid and measured with spectrophotometry.The method was simple,rapid and satisfactory.
