Abstract:Solid-phase extraction and HPLC were applied to the determination of acrylamide in paper. Acrylamide in paper was extracted with ultrapure water at 60℃, the aqueous extract was centrifuged and filtrated with 0.45 μm filter membrane, and then concentrated by Nitrogen evaporators. The concentrated liquid was purified by solid-phase extraction (SPE) and determined by HPLC. The limit of detection (LOD) of the developed method was 10 μg/kg. This method has the advantages of convenient operation, high sensitivity, excellent accuracy and good reproducibility and is therefore suitable for the determination of acrylamide in paper.
