Using sulfadiazine derivatives as a new azodyes reagents for the complexation and determination of aluminum

الملخص EN

This study involves the study of the complexation of three azodyes sulfadiazine derivatives, with aluminum.

The characterizations of complexes were studied, which confirming of forming stable azo dyes complexes.

The formation and stabilization of these complexes were studied by the optimum conditions, like time effect, pH effect at different values of pH (2-12) and sequence of additions.

The stoichiometry was found that the aluminium complexes form 1:2 (M:L) at pH value of 12.

The molar absorptivity coefficients, sensitivity and obeys of Beer's law were established .The interferences of others ions were also studied.

The stability (formation) constants of the complexes were determined by use of corresponding solutions method by aid of half-height method.

This method was found of good selectivity and high sensitivity for the determination of aluminum ions.
