This book deals with the physico-chemical principles underlying ion- exchange sorption and chromatog aphy. It does not cover in any detail the experimental and instrumental aspects of practical separations. The author has developed the subject starting from the synthesis and structure of the ion exchangers employed, through the thermodynamics of sorption selectivity and the equilibrium dynamics of ion sorption, to the kinetics and dynamics of non-equilibrium ion-exchange systems. Throughout this treatment the additional factors arising from the exchange of complex organic ions, as opposed to...
