Abstract: This study investigated the use of Hyphaene thebaica as a sorbent for remediation of crude oil polluted water. The crude Hyphaene thebaica (CHT), retted Hyphaene thebaica (RHT) and bleached Hyphaene thebaica (PFHT) were subjected to sorption studies to optimize their sorption capacity. The results revealed that the efficiency of sorbent to remove crude oil from water is related to the sorbent weight, contact time, initial oil concentration and temperature of sorption. It was found out that increase in sorbent weight led to increase in sorption capacity from 3.71-4.87g/g, 4.30-5.77g/g, and 4.56-6.23g/g in CHT, RHT and PFHT respectively. Increased in Initial oil concentration also increased the oil sorption capacity by 18-24% until it reach equilibrium. Sorption time was varied from 10, 20, 30, 40, 50, 60 and70 minutes and the highest sorption capacity was recorded at 30 minutes before a gradual decreased was observed. Sorption capacity decreased with increased in temperature above 400C. The sorbent exhibited good reusability after 8 cycles, with less than 50 % reduction in sorption capacity. These properties introduce Hyphaene thebaica as a potential sorbent for oil cleanup.

I. INTRODUCTION
Spillage of oil can occur anytime there is exploration, transportation and storage of oil and its derivatives; this can cause significant environmental impact. An area can be contaminated once an oil spill. Cleaning of oil from surfaces becomes more tasking when oil comes in contacts with something to cling to (e.g., beach, rocks, feathers of a duck or a bathers’ hair). Sea life, economy, tourism and leisure activities are all affected by pollution whenever there is oil spillage. Report has shown that about 10 million barrels of oil have been spilled both onshore and offshore in the Niger delta region of Nigeria [1, 2].
