Influence of polyfunctional interactions between organic zwitter-ion eremomycin and carboxylic cation exchangers on forming concentration front

The nature of the polyfunctional interactions between the organic zwitter-ions of eremomycin and the carboxylic sorbents was studied. A cation exchange and hydrophobic mechanisms of interactions in the studied sorption system were determined as preponderant over other ones. The typical features of the eremomycin diffusion into the pores of the structurally segregated carboxylic sorbents were studied. The physical–chemical properties of the sorption system which influence the formation of the target product concentration zone with sharp boundary were investigated. The effect of column sizes on the eremomycin unified elution peak formation was shown. The height to diameter ratio leading to the eremomycin concentration front division into two zones was determined.
