A kind of novel environmental-friendly composite absorbent material was designed and prepared in this paper.Nanoscale metal-organic frameworks(MOFs)were embedded in the skeleton of cotton micro fibrillated cellulose.By scanning electron microscope(SEM),we observed that a large number of MOFs were attached to the cellulose skeleton.In addition,under the condition of 1800 r/min vortex,the structure of the composite material was stable and was not easily damaged by external forces.The water contact angle test showed that the composite material had excellent hydrophilicity and could be used for the adsorption of pollutants.Then,the material was characterized by energy dispersive X-ray spectroscopy(EDX),X-ray diffraction(XRD),Fourier transform infrared spectroscopy(FTIR)and BET adsorption.Through verification,the material had very stable reusability(n=10).The composite material was applied to the solid phase extraction of water samples,such as rain water,toning water and fruit juice,and was quantitatively analyzed by high performance liquid chromatography(HPLC)-UV.This method was then applied to the extraction of four parabens(methyl-,ethyl-,propyl-,and butyl-paraben)from real samples,yielding limits of detection(LODs)of 0.29-0.58 ng/mL.The linear range was 2-500 ng/mL.The inter-day and intra-day recoveries were 90.7％-106.0％and 87.1％-109.3％,respectively(relative standard deviation＜10.8％).
