Nickel Iso-nicotine MOFs as Adsorbent of Solid Phase Extraction for Determination of Polycyclic Aromatic Hydrocarbon in Water

Xu-Yang Zhang, Bao-Hui Li, Xiao-Yan Li, Wan-Lin Yu


The method of solid phase extraction (SPE) combined with high performance liquid chromatography (HPLC) was established while nickel iso-nicotine MOFs was employed as adsorbent of SPE to concentrate eight kinds of PAHs in water. The chromatographic conditions, such as flow rate of mobile phase and composition of mobile phase, were investigated. Several important factors of extraction efficiency of SPE, including mass of absorbent, volume of water sample, content of methanol and pH were discussed. The detection limit, precision and recovery rate were calculated.
