Abstract
The present invention relates to a method for granulation of an absorbent and adsorbent granules prepared by the same. The method comprises the steps of blending sodium metasilicate, metakaoline and an inorganic ion exchange material in water to form a slurry; decanting the resulted slurry onto a nylon cloth of 300 to 400 meshes and natural drying at ambient temperature to solidification; then breaking the solidified final product and sieving it by a screen having a mesh size of from 0.2 to 2.5 mm to provide the absorbent granules having excellent absorbability.
