Summary: Biosorption using a chitosan-pectinase blend (CPB) was studied for the removal of methylene blue (MB) dye from synthetic solutions. The blend showed a rough surface morphology and amorphous nature. Fourier-transform infrared (FTIR) analysis confirmed the successful blend formation. Maximum adsorption was achieved at pH 7.0, 30°C, 30 min contact time, and an adsorbent dosage of 2.5 g/L. The pseudo-second-order model provided the best fit, with the highest R2 value close to 1. The Temkin isotherm model showed the highest adsorption capacity at 16.81 mg/g. The blend demonstrated good desorption ability, allowing for reuse in dye removal.

Summary: Chitosan/aspartic acid hydrogels were synthesized for the removal of MB dye from textile aqueous effluents. The hydrogels were characterized and confirmed to have successful preparations and MB dye adsorption. Batch experiments were conducted to investigate the effects of various factors on the adsorption process. The optimized conditions were determined for each hydrogel. The adsorption capacities of the hydrogels were compared, and both followed Freundlich isotherm model and pseudo-second-order kinetics for adsorption.
