Abstract
Dimethyl phthalate (DMP) was used as template molecule to prepare dimethyl phthalate imprinted polymer. The difference of characterization between MINFs and NINFs was analyzed by infrared spectroscopy (FTIR) and scanning electron microscope (SEM). The adsorption performance of imprinted nanofibers was studied through static experiment, isothermal experiment, and selective experiment, respectively. Simultaneously, the nanofibers was applied to analysis for water samples as packing material for solid phase columns. The results of adsorption kinetics showed that MINFs had high sensitivity and selectivity. MINFs showed better binding capacity than NINFs. The maximum binding capacity of MINFs was 4.6×10-2 mmol/g, and that of NINFs was 2.6×10-2 mmol/g. Solid phase extraction (SPE) was used to detect the concentration of DMP in real water samples, the recovery rate reaches 99.45%.
