Abstract

PURPOSE: To enhance the buffer capacity of a builder and reduce the treatment cost by neutralizing alkali hydroxide remaining in crystallized alkali aluminosilicate with acid or acidic salt followed by washing, filtration, etc.
CONSTITUTION: Zeolite is crystallized by a known method from a homogeneous composition composed of a silicic acid component, an alumina component, an alkali metal component and water within zeolite forming ranges. Alkali hydroxide remaining in the zeolite crystals is then neutralized with acid or its acidic salt under such conditions as make pH≥9. The crystals are optionally wahsed, filtered, and dried to recover zeolite-base powder. By this method the buffer capacity of the resulting builder can be enhanced remarkably while effectively preventing the zeolite crystals from being converted into sodalite with every low sequestering capacity during drying and heating. In addition, washing, etc. can be carried out easily.
