The surface derivatization of poly( p ‐phenylene terephthalamide) fiber was studied. The obtained surface‐derivatized filaments were packed into a fused‐silica capillary to evaluate its surface characteristics by using GC. As the stationary phase for GC the surface‐derivatized fibers showed higher retention for alkanes and alkylbenzenes than that with the untreated Kevlar fiber. The improvements on the retention power and the peak shape were observed on the benzyl‐modified fibrous stationary phase. The derivatized fibrous materials were also evaluated as the extraction medium in fiber‐in‐tube SPE, and the effect of the surface modification on the extraction power was compared to the parent fiber. The results indicated that the modified fiber possessed a higher extraction power than the untreated fiber. Based on the facts, the successful modification of the fiber surface was estimated.
