A stable mesoporous metal-organic framework as high efficient sorbent of dispersive micro solid phase extraction for the determination of polycyclic aromatic hydrocarbons by high performance liquid chromatography.
Journal of Separation Science 2018 September 20
Owing to the big molecular sizes of polycyclic aromatic hydrocarbons, adsorption of them using microporous sorbents leaded to low adsorption capacity. Here, to increase extraction capacity and detection sensitivity of polycyclic aromatic hydrocarbons, a highly efficient dispersive micro solid phase extraction method was developed based on a stable mesoporous metal-organic framework named Jilin University China 48. Jilin University China 48 is a super hybrid with large 1D hexagonal nanotube-like channels of 24.5 Å × 27.9 Å, which exhibits high potential to be an efficient sorbent of dispersive micro solid phase extraction to adsorb polycyclic aromatic hydrocarbons. By combining HPLC, a sensitive method was developed for the determination of seven polycyclic aromatic hydrocarbons. The synthesized Jilin University China 48 exhibited excellent characteristics of stability, good morphology, large surface area, and open adsorption sites. Under the optimized extraction conditions, better extraction results were obtained than that of other methods reported in previous literatures. The proposed method exhibited high sensitivity with the limit of detections of 0.021-0.13 ng/mL, good linearity in the range of 0.068-50 ng/mL with related coefficients of more than 0.9988, satisfactory precision with relative standard deviation of less than 4.3%, and adequate recoveries between 85.8% to 109.55% for all target compounds.
