Abstract: Pretreatment of the seed shell of Pentaclethra macrophylla Benth was carried out using 0.3 mol of thioglycollic acid. Biosorption analysis was conducted using different variations in the initial metal ion concentrations (100, 80, 60, 40, 20, and 10) mg/l at pH of neutral point, room temperature, contact time of 1 hr using 1 gram of the 250 mesh size of both the untreated and treated Pentaclethra macrophylla seed shells. Biosorption capacity of Pentaclethra macrophylla seed shell was observed to be high with increasing higher concentrations of the metal ions in both treated and untreated Pentaclethra macrophylla seed shells though maximum concentrations of Cd2+ and Pb2+ sorbed were observed by untreated Pentaclethra macrophylla seed shell while Ni2+ was highly sorbed by the treated Pentaclethra macrophylla seed shell. Data gotten via study gave good fit for different sorption isotherms such as Freundlich, Temkin and Dubinin-Radushkevich (D-RIM). Multilayer biosorption with non-uniform distribution over the heterogeneous surface was observed and the biosorption of the metal ions onto untreated and treated Pentaclethra macrophylla seed shells was spontaneous and was consistent with the pattern of physical adsorption.
