PREPARATION TERMOSTABLE ADSORBENT USING BENTONITE CLAY
Keywords:
adsorbent, bentonite clay, pillar structure, specific surface, zol, termostabilityAbstract
Preparation inorganic adsorbents using modifying bentonite clay with iron zol is considered. The samples of clay which undergoes acid treatment increase specific surface areas but do not thermostable, and loose their porosity above the temperature 1600C. For prevent from unthermostability bentonite clays treated by sol solution of iron hydroxide which give them pillar structural form. The charge of colloidial particles of sols hydroxide iron plays important role in formation of pillar structural form. Colloidial particles having positive charge were changed with ions containing between layers of montmorillonite mineral of bentonite clay. After modifying bentonite it shows thermostability until 5000C.
