Adsorption isotherms on aminoantipyrine imprinted polymer stationary phase.
Publication date: 2003
Abstract: The molecular imprinted technique was applied for the preparation of a polymer selector by using methacrylic acid as the functional monomer, EDMA as the crosslinker, AIBN as the initiator and aminoantipyrine as the template. The adsorption isotherms of aminoantipyrine, antipyrine, pyrazolone and the competitive adsorption isotherms of aminoantipyrine and antipyrine on the imprinted stationary phase were determined using rectangular pulse frontal analysis and static method. A solution of methanol-isopropanol (5:11) was used as the mobile phase in frontal analysis. it was found that the adsorption data fit well to both Langmuir and Freundlich isotherm models
