Agro wastes are vast abundant raw material whose potential is still under-utilized. Availability and biodegradability are a few features of these materials for utilization. The present study was aimed at exploiting the option of utilizing maize cob for remediation of industrial effluent. Maize cob was collected, pulverized and sieved into 150 -300 µm particle size. The carbonized materials obtained were then characterized using Energy Dispersive Xray (EDX) and Scanning Electron Microscope (SEM)

... for elemental and surface morphology determination. Standard solutions of Cr and Pb ion solution were prepared. The cob were used to treat effluent under the following conditions: agitation time (30 -150 min), adsorbent dosage (0.5 -2.5 g), metal ion concentration (5 -25 ppm) and particle size effect. From the result, 90 % and 38 % removal efficiency were obtained for Pb and Cr ions solution respectively. The potential of maize cob was established for the treatment of lead polluted wastewater.
