摘要
对ＧＢ７８１６－８７中光度法测定黄磷中砷含量的方法进行了改进。考察了黄磷样品制取方法，处理条件，如温度、酸度等对分析结果的影响。改进的方法具有样品易处理、分析速度快、节约试剂等优点。
It has been improved for spectrometric determination of arsenic content in phosphor.The effect of preparing phosphorous samples and analytical conditions,such as temperature,acidity,etc.on results were investigated.The proposed procedure had advantage of processing sample easily,fast analysis and saving reagents.
