Bio-sorption of Methylene Blue by Defatted Seed of Adansonia digitata

The study was carried to evaluate the ability of defatted seed Adansonia digitata (DFSE) remove methylene blue dye from contaminated water. optimum parameters such as contact time, particle size, absorbent dose, initial concentration, and pH were investigated by performing batch experiments models. kinetics isotherms adsorption evaluated varying concentration using parameters. time is 90 min removal capacity 99.34 %. A mass 700 mg sufficient reach maximum (99.44 %). obtained with an 75 ppm (98.53 size 100 mm. process are in accordance pseudo-second order model. Experimental values close proximity predicted Langmuir, Freundlich, Dubinin-Radushkevich Tempkin not suitable explain experimental isotherm.
