Immobilized Bentonite In Alginate Matrix – Efficient Sorbent Of Brilliant Green

Abstract

The environmental pollution by dyes has become an important concern due to the harmful effects on human health and entire ecosystem. In this study, bentonite immobilized in calcium-alginate (ImB) was studied as a sorbent for the Brilliant Green (BG) removal from aqueous solutions. The prepared composite sorbent was characterized by pHpzc, SEM and EDX. The sorption kinetic was best fitted by the pseudo-second-order model and simultaneously followed the film diffusion and intra-particle diffusion model during the sorption. This study proved that ImB might be an efficient sorbent for removing dyes from aqueous solutions.
