چکیده انگلیسی
Novel magnetic mesoporous molecularly imprinted polymers (MMIPs) were prepared based on surface precipitation polymerization using Triclosan (TCS) as template and methacrylic acid as functional monomer. The synthesized MMIPs-TCS were applied to the adsorbent of magnetic solid-phase extraction (MSPE) coupled with HPLC for the enrichment and determination of TCS. The MMIPs-TCS were characterized by fourier-transform infrared spectrometry (FTIR), scanning electron microscopy (SEM), transmission electron microscopy (TEM), N2 adsorption-desorption transmission, and vibrating sample magnetometry. Under the optimum condition, the MMIPs-TCS-MSPE-HPLC method shows low limits of detection (LODs) (0.20-0.90â¯Î¼gâ¯Lâ1) and limits of quantification detection (LOQs) (0.66-2.97â¯Î¼gâ¯Lâ1), wide linear ranges from 10.0 to 1000â¯Î¼gâ¯Lâ1 for each compound with exception of 2,4,6-TCP from 20.0 to 1000â¯Î¼gâ¯Lâ1, and acceptable reproducibility (relative standard deviation, RSD <6.6% for intra-day, RSD <8.1% for inter-day). The satisfactory recoveries were in the range of 89.5%-108.4% with good RSDs less than 8.0% at the three spiked levels of 20, 50 and 80â¯Î¼gâ¯Lâ1. Moreover, the adsorption experiments show the MMIPs-TCS possess rapid binding affinity, excellent magnetic response, specific selectivity and high adsorption capacity toward TCS with a maximum adsorption capacity of 1955.8â¯Î¼gâ¯gâ1.
