2. Principle

The adsorption mechanism is based on the highly polar surface of zeolite pores (i.e. the bonds are very low-energy). This unique feature (highly polar surfaces) distinguishes zeolites from other adsorbents on the market, and gives them a high adsorption capacity for water or other polar components. Zeolites can adsorb up to 30% of their mass in water. Adsorption must be distinguished from absorption, in which a continuous phase fills pores forming chemical bonds with solid matter (figure 4...
