DETERMINATION OF POLYCYCLIC AROMATIC HYDROCARBONS IN WATER USING NANOPOROUS MATERIAL PREPARED FROM WASTE AVIAN EGG SHELL

摘要

Nanoporous polymorphic crystals of CaCO₃ were used as sorbent and were applied in the dispersive micro-solid-phase extraction of selected polycyclic aromatic hydrocarbons as target analytes. After separation of the analytes on gas chromatography, they were successfully quantified with external calibration using flame ionization detection. Performance of the dispersive micro-solid-phase extraction was compared with a previously optimized solid-phase extraction technique.
