In this study, alginate-encapsulated biosorbents have been prepared from agricultural wastes viz. peanut shells and rice husks. Biosorbents in this study were referred as En-PS and En-RH for the adsorbents prepared from peanut shells and rice husks, respectively. The characteristics of the adsorbents were thoroughly investigated using scanning electron microscope, X-ray diffractometer, surface area analyzer, and Fourier-transform infrared spectrophotometer instruments. The prepared biosorbents were used as adsorbents for cationic methylene blue (MB) dye in water. The encapsulation process using sodium alginate simplified the separation of adsorbent from the water after the adsorption process. The adsorptions of MB onto both adsorbents followed the pseudo-second order model and fitted both Langmuir and Freundlich isotherm models. Thermodynamic studies revealed that the adsorption of MB onto En-PS and En-RH was a spontaneous and endothermic process with the ΔG° reaction of -1.694 and -2.028 kJ/mol at the room temperature, respectively. Biosorbents could be used in the adsorption-desorption process for up to 3 cycles.
