抄録

PS ash contains large amount of calcium carbonate. Calcium ion disturbs formation of zeolites from PS ash, resulting in that synthesizing zeolites was difficult. We synthesized both hydroxyapatite and zeolite from calcium carbonate and meta-kaolin in PS ash in the one batch system. The products were analyzed by XRD and the main component of product is hydroxyapatite and zeolite. Scanning electron microscopy relived that two components are incorporated in molecular level, showing a possible nano-composite materials. The products have been tested for ability in adsorption of acetaldehyde and methylene blue.
