The potential of human hair as an oil spill sorbent was investigated in this study by batch adsorption
experiments in vegetable oil, crude oil and diesel fuel. Three categories of human hairs were used: Type A
(Asian origin), Type B (European origin) and Type C (African origin). The order of performance based on
the sorption capacities was in the order: Type C > Type A > Type B. All hair types adsorbed three to nine
times their weight in oil. Maximum adsorption capacities of 9300 64, 8100 165 and 7917 72 mg/g
were achieved for Type C hair in vegetable oil, crude oil and diesel fuel, respectively. The sorption capacity
of human hair showed an inverse relationship with temperature for all the oils and sorption occurred on
heterogeneous sites with no uniform distribution of energy. Desorption and reusability test showed high
reusability without any significant deterioration in sorption capacity. The study demonstrated that
human hair has potential for use as a low-cost, effective and environmentally friendly biosorbent for oil
spill cleanup.
