摘　　要：测定了铋（Ⅲ）与对溴偶氮氯膦（ＣＰＡＰＢ）显色反应的电子光谱，λｍａｘ＝７３５ｎｍ．研究了ｐＨ值、ＣＰＡＰＢ用量和显色时间对配合物稳定性的影响，在最佳条件下确定了配合物的组成Ｂｉ（Ⅲ）∶ＣＰＡＰＢ＝１∶３．并用改善的яцииирскпй方法求出Δε３＝３．２２×１０４，β３＝１．９６×１０１３，配合物平均（表观）摩尔吸光系数的实验值Δε实验与其计算值Δε计算比较，基本一较．The electrospectrum of the color reaction of Bi(Ⅲ) with CPAPB has been determined,and a peak is found at 735 nm.The effect of pH、CPAPB and color time on stability of the complex have been studied.In the best condition,composition of the complex is Bi(Ⅲ)∶CPAPB=1∶3.It is caculated with Яипмпрскпй method that Δ ε 3=3.22×10 4, β 4=1.96×10 13 with are almost the same as exprimental results.
