摘要
本文用分光光度和拉曼光谱两种方法,对比研究了Triton X-100或聚乙烯醇(PVA)对结晶紫-磷钼杂多酸缔合物(CV-PMo)的增溶、增敏作用,在适宜的实验条件下,不论CV-PMo-Triton X-100体系,还是CV-PMo-PVA体系,都可用于在水相中分光光度测定痕量磷。本文还对这两类显色体系的有关反应机理,作了讨论和比较。
The enhancement effect of Triton X-100 or polyvinyl alcohol(PVA) on crystal violetphosphomolybdate (CV-PMo)chromogenic system has been investigated by spectrophotometry and Raman spectroscopy. Under suitable conditions, trace phosphorus in aqueous solution can be determined either by CV-PMo-Triton X-100 system or by CV-PMo-PVA system. The mechanism of these two chromogenic systems have been discussed.
