Strong aggregation adsorption of methylene blue from water using amorphous WO3 nanosheets
Source abstract
Abstract
Abstract In this paper, authors demonstrate the high performance of the amorphous WO3 nanosheets in the removal of methylene blue (MB) from water. The saturated MB adsorbed amount by using WO3 nanosheets as an adsorbent can reach to 600 mg/g, exceeding the ones of the normal activated carbon powders. Results indicate that the aggregation of adsorbed MB molecules occurs in the porous micro-structures of the amorphous WO3 nanosheets, and a precipitation phenomenon begins to happen when the initial MB concentration reach to 20 mg/L or greater, attributed to the density increase of WO3 nanosheets after their porous micro-structures are adsorbed with enough MB molecules.
