Sulfamethoxazole-imprinted polymer for selective determination of sulfamethoxazole in tablets

A sulfamethoxazole (SMO)-imprinted polymer (MIP) was prepared in acetonitrile using the mixture of acrylamide and 4-vinylpyridine as functional monomers. The molecular recognition properties of the polymer was evaluated in both acetonitrile and aqueous acetonitrile mobile phases. SMO contents in two kinds of tablets were determined satisfactorily using the MIP packed HPLC column with aqueous mobile phase. (C) 2004 Elsevier B.V. All rights reserved.
