| Abstract: | The synthesis of a new reagent 6\-Methoxy-Benzothiazolyldiazoamino-2,6-Dibromo-4-Carboxyphenyl (MBTDABPCP) and its color formation reaction with Cd(Ⅱ) are reported.In weak alkaline medium Na247-HCl(pH=8.5) and in the presence of SDS,Cd(Ⅱ) reacts with reagent to form a orange-yellow complex.The interference of various ions has been studied and the method used for the determination of micro amounts of Cd(Ⅱ) in wastewater. |
