The present studied has been undertaken to study sorption efficiency of diesel oil from water bodies using agricultural waste Zea mays cob powder. The influence of biomass dosage, contact time, particle size and volume of water on the removal process was investigated. Batch studies indicated that maximum sorption efficiency of diesel oil was 72 % at contact time (30 min), particle size (105 μm) and volume (100 ml). FTIR & SEM micrographs of native and oil loaded cob powder confirmed diesel oil sorption phenomenon. Petroleum ether was used for regeneration for several cycles with a view to recover the sorbed diesel oil and also to restore the sorbent for its reuse. The findings showed that Zea mays cob powder can easily be envisaged as a new, vibrant, low cost biosorbent for diesel oil clean-up operations.
