| Abstract: | A new triazene reagent for spectrophotometric determination of cadmium 2. 6 - diiodo - 4 - sulfamoylbenzenediazoaminoazobenzene (DISDAA ) was synthesized and purified in this paper. In the presence of nonionic surfactant TritonX -100 the color reaction of the reagent reacted with cadmium was studied. The results of color reaction was compared with homologous reagents 2. 6-dichloro - 4 - sulfamoylben-zenediazoaminoazobenzene ( DCSDAA ). 2. 6 - dibromo - 4 - sulf amoylbenzenedia-zoaminoazobenzene ( DBSDAA) and p - sulfamoylbenzenediazoaminoazobenzene (SDAA)which had been synthesized by author in the recent year. The relationship between the reagent structure and their analytical properties was dissueed. |
