Using Sulfadiazine Derivatives as a New Azodyes Reagents for the Complexation and Determination of Aluminum

Abstract

This study involves the study of the complexation of three azodyes sulfadiazinederivatives, with aluminum. The characterizations of complexes were studied, whichconfirming of forming stable azo dyes complexes. The formation and stabilization ofthese complexes were studied by the optimum conditions, like time effect, pH effectat different values of pH (2-12) and sequence of additions. The stoichiometry wasfound that the aluminium complexes form 1:2 (M:L) at pH value of 12. The molarabsorptivity coefficients, sensitivity and obeys of Beer's law were established .Theinterferences of others ions were also studied. The stability (formation) constants ofthe complexes were determined by use of corresponding solutions method by aid ofhalf-height method. This method was found of good selectivity and high sensitivityfor the determination of aluminum ions.
