Layer-Structured Fe-Aminoclay/Carboxymethyl Cellulose/ POSS Adsorbent for the Removal of Radioactive Cesium and Cationic Dyes |
초록 |
Multifunctional Fe-aminoclay (FeAC)/carboxymethyl cellulose (CMC)/polyhedral oligomeric silsesquioxane (POSS) composite (FeAC/CMC/POSS) with layered structure was successfully synthesized and utilized as adsorbent for the removal of cesium ions (Cs+) and cationic dyes methylene blue (MB) and chrysoidine G (CG). The FeAC/CMC/POSS exhibit excellent adsorption capacities for Cs+ ions, MB and CG of 152, 438 and 791 mg g-1, respectively. The unprecedented adsorption capacities for Cs+ ions, MB and CG may be attributed to (i) the layered morphology of the composite and–NH2 groups on clay surface; (ii) existence of–COO- and–OH- groups on the CMC backbone. More importantly, the incorporation of POSS increases the interlayer spacing of Fe-aminoclay providing room for the encapsulation of Cs+ ions and dye molecules. The devised FeAC/CMC/POSS composite could be a promising organic-inorganic material used to cost-effectively remove the multitude of environmental pollutants. |
