Decoration of Chitosan-Benzaldehyde/Algae/Coal Fly Ash Adsorbent for Brilliant Green Dye Removal: Box-Benken Design Optimization and Mechanism Approach
This study involved the development of grafted chitosan-benzaldehyde/algae/coal fly ash (CS-BD/Alg/FA) to be a promising adsorbent for cationic dye namely brilliant green (BG) dye. The adsorption of brilliant green (BG) dye was optimized using Box-Behnken design (BBD) resulting in the determination...

This study involved the development of grafted chitosan-benzaldehyde/algae/coal fly ash (CS-BD/Alg/FA) to be a promising adsorbent for cationic dye namely brilliant green (BG) dye. The adsorption of brilliant green (BG) dye was optimized using Box-Behnken design (BBD) resulting in the determination of the optimal adsorption variables. A dosage of 0.07 g/100 mL of CS-BD/Alg/FA resulted in a 97.5% removal of BG dye when the pH was set at 10 and the duration of the adsorption process was 480 min. The adsorption kinetic and isotherm data obtained under optimal conditions suggested that the adsorption of BG by CS-BD/Alg/FA obeyed the pseudo second order (PSO) and Langmuir monolayer adsorption respectively.
