The use of base modified sweet potato leaf (BSPL) was demonstrated as an effective adsorbent for the removal of cobalt, zinc and cadmium ions using the batch adsorption process. The biosorption properties of the adsorbent for metal ions were evaluated for sorption time, initial concentration of the contaminants, pH, sorbent dosage and temperature. Maximum uptakes of metal ions were attained after 100 minutes for Zn2+and Cd2+ ions and at 150 minutes for Co2+ ions. Kinetic analysis of the adsorption data revealed that the biosorption data were best described by the Pseudo-second-order model(R2 >0.95). It was also apparent that the data best fitted the Langmuir model, which yielded a maximum adsorption capacity of 3.879, 4.069 and 4.368 mg.g-1 for Zn2+, Cd2+ and Co2+ respectively. Analysis of calculated thermodynamic parameters affirms that the biosorption process is feasible, spontaneous, and endothermic. Evaluated entropy change (ΔS) for the adsorption processes were 162.12, 171.93, and 174.93 J.mol-1.K-1 for Co2+,Zn2+, and Cd2+ ions respectively which is in agreement with the expected randomness of the system. Prominent infrared absorption bands which could be involved in the adsorption process included –OH, -NH2, C=C, C=O, and C-O functional groups, while SEM analysis showed agglomeration of round particles shapes on the surface structure of the biomass. Thus, base-modified sweet potato leaves can be used as an excellent adsorbent to sequester toxic metal ions from wastewater
