Refinery wastewater is a rich source of heavy metal ion contaminant and may not be safe if directly discharge to the environment without pre-treatment. This study seeks to implements application of various activated carbon adsorbents for the removal of cobalt and manganese ions from refinery waste water. The adsorbent produced include; ACDMPA (Activated carbon from Detarium microcarpum, using H3PO4 as activating agent), ACDMZC (Activated carbon from Detarium microcarpum, using ZnCl2 as activating agent), ACBAPA (Activated carbon from Balanites aegyptiaca, using H3PO4 as activating agent) and ACBAZC (Activated carbon produced from Balanitea egyptiaca, using ZnCl2 as activating agent). Influence of initial concentration, contact time, pH and adsorbent dosages were investigated and the results indicated that optimum pH for the removal of Mn2+ by all the adsorbents was 2, while the optimum pH for the removal of Co3+ was 4 by ACDMPA and CAC. At pH 6, the maximum adsorption of Co3+ occur when ACDMZC, ACBAPA and ACBAZC was used. An equilibrium time of 30 minutes was required for the adsorption of Mn2+ and Co3+ by CAC, while 45 minutes was the equilibrium time for the adsorption of the two metal ions onto ACDMPA, ACDMZC, ACBAPA and ACBAZC. The optimum dosage for removal of Co3+ was 0.4g when CAC and ACDMPA was used, and 0.6g when other adsorbents were used. For Mn2+ the optimum dosage for its removal was 0.4g when ACDMPA was used, while 0.6g was the required optimum dosage for other adsorbents. The adsorbent produced were effective for the removal of Mn2+ and Co3+
