摘    要:本文发现, AuCl4^-在KOH和H2O2存在下会产生弱化学发光信号; 在此基础上建立了AuCl4^-H2O2-KOH-CTMAB体系测定金的新的简单的化学发光分析法; 方法的检测限为5.5ppbAn; 线性范围为10-800pph; 测定100ppb金溶液的相对标准偏差为6.5%; 并初步探讨了AuCl4^-化学发光的可能过程及表面活性剂的影响作用。

关 键 词:  表面活性剂  氯化物  四元系  过氧化氢  化学发光分析  氢氧化钾  金化合物  化学发光  溴化十六烷基三甲铵

Abstract:Chemiluminescence was generated from the system of AuCl4--H2O2 and KOH, and the addition of cationic surfactant CTMAB (cetyltrimethylammonium bromide) was able to increase the sensitivity and the stability of the chemiluminescent system. A new chemiluminescent method for the determination of gold was thus established, and was used to determine gold in ores. The detection limit is 5.5 ppb Au. The linear range is from 10 to 800 ppb Au. It is suggested that the O2 produced existed in the excited state, which was responsible for the generation of chemiluminescence. The role of CTMAB is discussed.
