Abstract
Oil palm empty fruit bunch (OPEFB) fibers were modified with silylation by trimethylchlorosilane (TMCS) and diethyldichlorosilane (DEDCS). The investigation was carried out at room temperature at a concentration of 1, 3, 5, and 9%wt and aging time of 3, 5, and 9 hr. Fiber modification was conducted by leaching out surface contaminants resulting in open porous surface. An optimal condition to reach the equilibrium silylation reaction was undertaken at a concentration of 1%wt and aging time of 3 hr. The sorption of oil which was emulsified in water on fresh and silylated OPEFB fibers fit Temkin and Langmuir isotherms, respectively.
