Abstract: The use of agricultural wastes in the treatment of metal-bearing effluents is one of the recent techniques that had been found to be environmental friendly. This work recommended the coat of fluted pumpkin seed a good biosorbent through adsorption process in a batch experiment. Variation of important operational parameters such as pH and temperature were used to explore their effect using 1 g of 250 μm size of both unmodified and mercaptoacetic acid modified fluted pumpkin seed coat at contact time of 1 hr with initial metal ions concentration of 100 mg/l. The adsorption efficiency of the metals was pH as well as temperature dependent with nearly 100% adsorption by both unmodified and modified fluted pumpkin seed coat. Specifically, cadmium was adsorbed more strongly at low pH of 2, 4 & 6 by the unmodified coat of the fluted pumpkin seed while it was at higher pH of 10 by the modified seed coat. The same is applicable for nickel which indicated higher adsorption at 2 by the unmodified seed coat and 10 by the modified one while higher adsorption for lead was shown at pH of 2 for both unmodified and modified ones. Maximum adsorption was equally achieved at low temperature (303K) by both unmodified and modified seed coats, though unmodified seed coat showed slightly higher adsorption than the modified seed coat. The values of Ea, , gotten indicated that the adsorption process is by physical adsorption, spontaneous, feasible and exergonic (release of free energy), endothermic and occur with increasing degree of orderliness.
