摘　　要：首次报道了聚乙烯醇缩对甲酰基偶氮氯膦（简称：ＰＶ·ＣＰｐＦ）的合成、纯化及其鉴定方法，并初步探讨了在光度分析和非有机溶剂萃取分离方面的应用。结果表明，小分子显色剂高分子化后，其分析性能有了明显改善，特别是显色灵敏度和萃取率均有不同程度的提高。A w ater-soluble polym eric reagent polyvinyl alcohol condensed p-form ylchloro- phosphonazo(PV·CPpF) has been synthe- sized for the first tim e by condensing p- form ylchlorophosphonazo with polyvinylalco- hol, a detailed study on m ethods ofits purifi- cation and identification has been m ade, and its application to photom etric analysis and nonorganic solventextraction separation have also been explored. The analyticalbehaviorof this group of reagents condensing w ith PVA show ed certain im provem ent in chrom ogenic sensitivity and extraction rate.
