邻-羟基偶氮基团是具有更高灵敏度的铍试剂的功能团,偶氮氯膦Ⅰ或Ⅲ正具有此基团。文献研究了偶氮氯膦Ⅲ对铍的萤光及显色反应。但至今未见报导偶氮氯膦Ⅰ对铍的测定。本文探讨了铍与偶氮氯膦Ⅰ的络合反应,络合物最大的吸收于580nm,此处摩尔吸光系数为8.89×10~3,络合物组成1:1。本文拟定的分析流程简单快速,适于直接测定矿石中0.x～x%的氧化铵。
O-hydroxyazo group is a functional group of the beryllium reagent with higher sensitivity, and chlorophosphine I or III has this group. The literature studies the fluorescence and color reaction of azlochlorophosphine Ⅲ to beryllium. However, so far no reported chlorophosphonazo I beryllium determination. In this paper, the complexation of beryllium with chlorophosphonazo Ⅰ was studied. The maximum absorption of the complex at 580 nm was found. The molar extinction coefficient was 8.89 × 10 ~ 3 and the complex consisted of 1: 1. The analytical procedure developed in this paper is simple and fast, suitable for direct determination of 0.x ~ x% of ammonium oxide in ore.
