文摘

Novel hollow porous ionic liquids composite polymers were fabricated. Prepared polymers showed high binding capacity and fast binding kinetics. Online SPE–HPLC system were developed and validated. Online system has good accuracy, precision, and convenience. The method could selective analyze hydroxybenzoic acids from complex matrices.
