黄磷中多核芳烃的紫外光谱测定

Determination of polynuclear aromatics in yellow phosphosus by ultraviolet and visible spectrophotometry

多核芳烃是黄磷中的有机污染物,直接影响了黄磷的品质.研究了通过紫外光谱法测定黄磷中多核芳烃的测定方法.结果表明,黄磷中多核芳烃的含量均在0.387—0.148吸光度/g.该方法快速、灵敏、准确.

Polynuclear aromatics in phosphorus are considered organic contaminants,and have great effect on the grade of yellow phosphorus.Method for deterrninatnoin of PNA in yellow phosphorus was reported.It was found that a sample contained 0.387—0.148 adsorbance/g.This method is fast,sensitive and accurate.
