environment could cause several diseases to man, animals and even plants. Therefore, efficient removal system of these drugs is paramount. Adsorption isotherm parameters for adsorption of Chlorpheniramine (CHP), Ibuprofen (IBU) and Glipizide (GLI) using OAC, HAC and BAC of mango kernel seed was examined in this study. Activated carbons (ACs), Oxidized activated carbons (OAC), hydrophobic activated carbons (HAC) and basic activated carbons (BAC) prepared from mango kernel seed were employed in this study. ACs were prepared from mango kernel seed (MKSAC), through KOH activation. The ACs were oxidized with HNO3 to produce OACs that were surface functionalized using ethylene diamine to produce BACs and ethylamine to produce HACs. The adsorption isotherm parameters were comparatively determined. From our result, equilibrium adsorption was reached faster on HAC and OAC than on BAC with kinetic adsorption data following well pseudo second order model much better than pseudo first order and intra-particle diffusion. Equilibrium adsorption data follow well the Langmuir model than the Freundlich model. The CHP uptake follows the order: HAC > OAC > BAC whereas the adsorption of IBU and GLI follow the order: OAC > HAC > BAC for mango kernel seed. OAC, HAC and BAC of mango kernel seed showed good potential for Chlorpheniramine, Ibuprofen and Glipizide removal from pharmaceutical liquid waste.
