Abstract

An investigation was made of the thermal behaviour under non-isothermal conditions of a series of low-acidity synthetic cationites having a methacrylic-divinylbenzene (DVB) matrix, such as Amberlite IRC 120, Ionenaustauscher IV Merck, Vionit CC1, and Purolite C104, C105 and C106. The macroporous, macroreticular and gel cationites were in acidic or sodium form, with various granulations and degrees of cross-linking. The apparent kinetic parameters (reaction order, n, activation energy, E, and pre-exponential factor A) were evaluated for two dehydration processes and the effects of the experimental conditions on these parameters were investigated.
