Abstract: An S-naproxen (S-NAP) molecularly imprinted monolithic stationary phase (MIMSP) with specific recognition for S-NAP and naproxen (NAP) was prepared by in situ technique, utilizing 4-vinylpridine (4-VP) as a function monomer, ethylene glycol dimethacrylate (EDMA) as a cross-linking agent, and low-polar solvents (toluene and dodecanol) as porogenic solvents. The selectivity of the polymers for S-NAP and NAP was evaluated by high performance liquid chromatography (HPLC). The binding characteristics were tested by Scatchard analysis. Racemic NAP could be specifically separated to some extent. At the same time, NAP could be separated from ibuprofen under optimized conditions. Scatchard analysis showed that two classes of binding sites existed in the S-NAP-imprinted polymers, with their dissociation constants estimated to be 1.045 and 5.496 μM, respectively. The results demonstrate that S-NAP and NAP can be recognized specifically on the obtained MIMSP.
