Abstract

ABSTRACTUse of solvent impregnated resin in the separation has emerged as a new area of interest. It is a hybrid process with the characteristics of adsorption, ion-exchange and extraction. Here, Aliquat 336 impregnated Amberlite XAD-4 resin was used to remove Rhodamine-B and malachite green individually and from their mixtures in the aqueous solution. The performance of prepared resin was studied in batch mode to analyze the effect of adsorbent dosage, pH, concentration of dye solution, salt concentration, time, and temperature. Characterization (using FE-SEM, EDS, FTIR, and point of zero charge), regeneration, and cost analysis of the adsorbent were also done.
