Extraction and Separation Processes

Experimental work on the thermal stability of cation-exchange resins in air, water, certain aqueous solutions, and also organic media is summarised for the first time. Conclusions are reached about the effect of various factors on the thermal stability and about the nature of the processes responsible for the decrease in exchange capacity. Special attention is paid to the existence of an inherent relation between the thermal stability and the catalytic activity of ion-exchange materials. A list of 235 references is included.
