Removal of Reactive Dye Using Solvent Impregnated Resin

Abstract

In this study, Reactive Blue-13 (RB-13) dye removed by solvent impregnated resin (SIR: Amberlite XAD-7 impregnated with Aliquat-336) at different operation conditions. Batch adsorption studies were dispensed out to gauge the effect of solution pH, dosages, kinetic, temperature, concentration and NaCl salt on the adsorption capacity of the adsorbents. Three kinetic models were chosen to suit the kinetic data; pseudo first order, second order, and intraparticle. diffusion. It had been determined that RB-13 dye adsorption followed pseudo-second-order kinetics. Adsorbent SIR was characterized by Fourier transform infrared spectroscopy (FTIR), Scanning electron microscope (FE-SEM) and EDX. Solvent impregnated resin (SIR) was regenerated with 80% (v/v) ethanol aqueous solution for reuse.
