Preparation and Study of Naproxen Imprinted Monolithic Columns based on MCM41 Doping
In this study,MCM41-MPS-doped naproxen imprinted monolithic columns were successfully synthesized by molecularly imprinted technique with in situ polymerization.By improving the formulation and then examining the chromatographic conditions,an imprint factor of up to 10.7 was achieved,which was more than two times higher than that of the undoped MCM41-MPS imprinted monolithic column.The results showed that MCM41-MPS MIP had higher retention and blotting factors than MIP,and the polymer was characterized by Fourier infrared absorption spectroscopy(FT-IR)and scanning electron microscopy(SEM),and the maximum adsorption amount of MCM41-MPS MIP was obtained to be 10.89 mg/g by using Langmuir fitting,and ultimately,the spiked lake water was spiked with naproxen was subjected to solid phase extraction with a recovery of 96.40%.
