Abstract: Erythromycin molecularly imprinted membranes (EM-MIMs) were prepared by MAA as functional monomer, EDMA as crosslinker in the presence of erythromycin as template. The influences of the proportion of EM and MAA, cross-linking use level, different initiators and use level as well as extraction time on the imprinted sites and specific separation of EM-MIM for EM were investigated. The results show that EM-MIM would obtain more imprinted sites and more excellent separation properties for EM when adding MAA 0.0461mol, EM 0.724mmol, AIBN and (NH4)2S2O8 each 0.12g as initiators, and the mole ratio of EDMA to MAA at 5:1.Erythromycin molecules as templates were extracted by ultrasonic oscillating for 40min, using absolute ethyl alcohol as eluant
Template and target information: erythromycin
