4-(2-吡啶偶氮)-间苯二酚(PAR)是很多金属离子的良好分光光度试剂和络合指示剂。为此本文将PAR引入交联聚苯乙烯珠体,制得连接4-(2-吡啶偶氮)-间苯二酚功能基的螯合树脂(简称PAR树脂)。研究了其分析特性并已用于铀矿区废水中铀含量的测定,取得了满意的结果。
4- (2-pyridylazo) -resorcinol (PAR) is a good spectrophotometric and complexing indicator for many metal ions. For this purpose, PAR was introduced into crosslinked polystyrene beads to prepare chelate resin (PAR resin) linked with 4- (2-pyridylazo) -resorcinol functional group. The analytical properties have been studied and have been used for the determination of uranium in wastewater from uranium mining area. The satisfactory results have been obtained.
