In this study, chemically synthesized activated carbon was produced from corn cob biomass using ammonium sulphate ((NH4)2SO4 as an activator at certain technical conditions. The proximate analysis of the product revealed 10.65± 0.0707 % moisture content, 29.05± 0.005 % volatile matter, 29.7 ± 0.1414% ash content and 69.4% fixed carbon. The adsorption capacities of with the three dosages (1, 2 & 3g) across the range of 5, 10,15,20,25 & 30 minutes with the solution of anhydrous potassium phosphate were justified with the models; y = -0.0116x2 + 1.773x + 57.536 at RČ = 0.9551, y = -0.0471x2 + 2.1177x + 77.769 at RČ = 0.9373 and y = -0.0161x2 + 0.742x + 91.924 at RČ = 0.9632 respectively. These findings suggest that chemically synthesized activated carbon from corn cob using ammonium phosphate as an activating agent is a potential adsorbent for the elimination of contaminants from water.
