本文研究了在CTMAB-SLS混合表面活性剂体系内,新试剂Br-BTAQ的光度特性及其与铋的反应性能,并拟定了测定铋的分光光度法。配合物的表观摩尔吸光系数为1.68×10~5l.mol~(-1).cm~(-1)。
In this paper, the photometric properties of Br-BTAQ and its reaction with bismuth in the CTMAB-SLS mixed surfactant system were studied. A spectrophotometric method for the determination of bismuth was developed. The apparent molar absorptivity of the complex is 1.68 × 10 ~ 5l.mol ~ (-1) .cm -1.
