Research of the activity of Fe-pillared montmorillonites in aqueous dye solution

High specific surface area, large micropore volume, concentration of acid sites, and increased density sorption sites make montmorillonite pillared as an excellent adsorbent catalyst to remove contaminants from wastewater. The studies are aimed at establishing the adsorption catalytic activity Fe based on Krantau Navbakhor bentonite in relation dyes solutions. It has been shown that introduction 3+ ions into interlayer space a natural sample increases with respect anionic dye by more than 2 folds. Despite area original clay, compared for Congo red is greater pillar latter. established Fe-pillared materials active catalysts oxidation hydrogen peroxide aqueous solutions lead its 100% conversion.
