The objective of this work is to study the removal of violet 5R azo dye by adsorption on powdered activated carbon. Following for kinetics adsorption showed that the best results were obtained after 10 minutes of agitation of a solution of 100 ml of violet 5R 10-4M with 10 mg/l of PAC. The initial amount of the dye and the pH of the medium influence greatly the rate of retention.
The objective of this work is to study the possibility of removal of orange 16 azo dye by adsorption on powdered activated carbon and the effect of different reaction parameters. During the experimental study, adsorption tests were carried out in reactor static solutions of this compound in distilled water. Following for kinetics adsorption showed that the best results were obtained after 15 minutes of agitation of a solution of 100 ml of orange 16 10-4M with 10 mg of PAC. The initial amount of the dye and the pH of the medium influence greatly the rate of retention.
