Abstract:  
The objective of this work is to investigate the use of human hair, sheep hair and remnants of the army woven fiber like pullover and blanket for oil spill removal. These materials are available in Egypt as waste materials. Hair is gathered from parlors and barber shops. Remnant of second hand military blankets and second hand military knitted pullovers are widely available. Several factors have been varied to study their effect on the sorption capacity of four materials used as sorbents. These factors are: effect of sorption time, effect of sorption weight, effect of temperature on sorbent, effect of oil film thickness on sorbent, reusability of sorbent, effect of sorption / desorption. It is found that the best conditions are at sorption time 30 min that oil sorption capacity by human hair reaches 7.7 g oil / g human hair for one day weathered crude oil, 12.16 g oil / g human hair for seven days weathered crude oil and 7g oil / g human hair for gas oil. It is found that the best conditions are at sorption time 30 min the oil sorption capacity which reached a value for second hand military blanket in 30minutes of 6.2 g oil / g blanket for one day weathered crude oil, 6.5 g oil / g blanket for seven days weathered crude oil and 4.4 g oil / g blanket for gas oil and for second hand military knitted pullover are at 30 minutes the oil sorption capacity which reached a value of 8.19 g oil / g pullover fiber for one day weathered crude oil, 5.6 g oil / g pullover fiber for seven days weathered crude oil and4.94 g oil / g pullover fiber for gas oil and for sheep hair the oil sorption capacity which reached a value in 30 minutes of 9.44 g oil / g sheep hair for one day weathered crude oil, 13.4 g oil / g sheep hair for seven days weathered crude oil in 15 minutes and7.6 g oil / g sheep hair for gas oil in 30 minutes. This means that the most efficient sorbents to be used for oil spill cleanup are sheep hair and human hair, respectively then second hand military blanket and second hand military knitted pullover. Comparison between the four materials used as sorbents and tough bag as se, rice hull as agricultural waste and (Absorbed-IT filtration fabric grey colored sheet and Adsorbed-IT filtration fabric white colored sheet) as commercial sorbents is done. It is found that the sheep hair and human hair have higher sorption capacity than others.
