Аннотация: The sorption—desorption kinetics of nicotinic and isonicotinic acids on strong acid cationites (sulfocationite CU-2-8, sulfonated polycalixarene) were considered. The rate of the processes, following both the cation exchange mechanism H+ ⇄ Cat+ and the ion exchange mechanism accompanied by the chemical reaction of protonation of pyПоказать полностьюridinecarboxylic acid zwitterions, is determined by a slow diffusion of components in the polymeric phase. The interdiffusion coefficient in sulfocationite CU-2-8 for the process H+ ⇄ Cat+ was equal to ~1•10–11 m2 s–1, in sulfonated polycalixarene the corresponding value was in the range of (1—4)•10–12 m2 s–1. © 2017, Springer Science+Business Media, LLC, part of Springer Nature.
