CELLULOSE MICROSTRUCTURES-TEMPLATED NANOCOMPOSITES WITH ENHANCED ARSENIC REMOVAL CAPACITY AND A PURIFIER THEREOF

摘要

ABSTRACT The present invention relates to the method of preparing microcrystalline cellulose-based composites as adsorbents for water purification and related applications. The composite comprises an aggregated network of cellulose microcrystal and its derivatives templated 2-line iron oxyhydroxide. The granular composite acts as an active ingredient used for arsenic removal As(III) and As(V) from water with capacity greater than 98 mg/g, wherein the filtered water has an arsenic concentration below 10 parts per billion.
