Read Morenatural zeolites are interesting materials to perform these processes. The selectivity of a sorbent depends on the ionic radius, cation charge, zeolite structure, distribution of active centers, and the temperature of the process (9). The efficiency of the sorption process depends on the pure zeolite content in a mineral,
