Alexandra Raluca MIRON, ABBAS ABDUL KADHIM KLAIF RIKABI, ALEXANDRA-GABRIELA NICULAE, SZIDONIA-KATALIN TANCZOS Kinetic Study of Alizarin Saphirol and Indigo Carmine Dyes Adsorption Process

Abstract:

Electrocoagulation is an electrochemical method based on the in situ generation of coagulating agents by sacrifical anodes use. In this paper we aimed to study the adsorption process kinetics of two dyes with multiple industrial uses, namely, Indigo Carmine and Alizarin Saphirol. Also, the influence of current density and initial pH value on adsorption process kinetics was evaluated. The results revealed that on aluminum anodes, the highest adsorption process rates and the lowest half - time values were obtained at pH = 6. In the case of iron anodes use, we have noticed that the half-time decreased with increasing pH and the initial adsorption rate values increase with pH increasing. Keywords: adsorption, electrocoagulation, dyes removal, kinetic modelling
