| Abstract: | Anew color reagent for the spectrophotometric determination of cadmium, 2-carboxyl-4-bromobenzene diazoaminoazobenzene, has been synthesized and the color reaction between the reagent and cadmium in the presence of Trito X-100 has been studied.By comparing the above color reaction with the color reaction of analogous reagents o-carboxylbenzenediazoaminoazobenzene,m-carboxylbenzenediazoaminoazobenzene, p-carbolylbenzenediazoaminoazobenzene, 2,4-dibromo-6-carboxylbenzenediazoaminoazobenzene and 2, 6-dibromo-4-carboxylbenzenediazoaminoazobenzene with cadmium respectively, the relationshipbetween the structure of reagent and analytical properties has been discussed. |
