摘　　要：本文应用吸收光谱、激光拉曼光谱及量子化学方法研究了5-Cl-PADAB及其钴络合物在不同酸度溶液中存在的形式及络合生色反应的机理,测定了钴络合物的质子化常数。The various forms of 4-(5-chloro-2-pyridylazo)-1, 3-diaminobenzene(5-Cl-PADAB) and its complex with cobalt in the different acidities solution have been studied by absorption spectrometry, Raman spectrometry and quantum chemistry. The mechanism of complexation between cobalt and 5-Cl-PADAB has been studied. Protonation constants of the colmplex were determined.
