Abstract

In this study, poly (amidoamine) G-2 dendrimer (PAMAM-G2) were applied as adsorbents for the removal of the dye from the effluent containing dye BASIC VIOLET 16 (BV16). With increasing pH, contact time and initial dye concentration, increased absorption capacity qe., While the amount of adsorbent, the adsorption capacity was inversely. Which can be attributed to reduced competition among dye molecules to bind to the sorbent. The optimum conditions for dye absorption was determined at pH 11.8, the amount of absorbent 0.6 gr.L-1, dye concentration 40 mg.l-1 and contact time 100 min. Among the factors studied, pH has provided the greatest impact on the absorption capacity and the percentage of DYE REMOVAL. So that by changing the pH from 8 to 11.8, increased the percentage of DYE REMOVAL from 68 mg.gr-1 to 102 mg.gr-1. Isotherm equilibrium was consistent with Langmuir isotherm models, Freundlich and Temkin. The results show good agreement with Langmuir isotherm model with a correlation coefficient 0.994 and the maximum absorption capacity was evaluated at optimal conditions mg.g-1 114.38. For ADSORPTION KINETICs data, was used three models Pseudo-first-order, pseudo-second-order and influence between the particles. The sorption kinetics in the absorption process followed the pseudo-second-order and intraparticle diffusion models. That is very close to the experimental value, and represents the ability to control the absorption process by chemical agent concentration and intraparticle diffusion. The results indicate the proper efficiency and absorption capacity in removal of BV16 by the PAMAM-G2 dendrimer.
