| 1 | Removal of Anionic Dyes from Aqueous Solution with Layered Cationic Aluminum Oxyhydroxide显示文摘It is highly desired yet challenged to find an adsorbent with low cost and excellent performance in the removal of organic dyes from aqueous solution. Here we reported that a layered cationic aluminum oxyhydroxide material hydrothermally synthesized from the low-cost source materials of AlCl_(3)·6H_(2)O, CaO and H_(2)O, known as JU-111, can meet such criterion in removing methyl orange(MO) and Congo red(CR). JU-111 shows fast adsorption kinetics[especially for CR(15 s)] and high adsorption capacity(MO: >1000 mg/g;CR: >2900 mg/g), surpassing most of the reported adsorbents. Comprehensive characterizations of the adsorption process of MO and CR revealed that both adsorptions were achieved via the anion exchange process. The characteristics of extremely low cost and excellent performance render JU-111 great potential in the practical applications in the removal of anionic dyes. | ZHANG Tianran YU Huacheng WANG Wenkai BAI Pu JIN Keyan ZHANG Jia-Nan YAN Wenfu | 2022 | Chemical Research in Chinese Universities2022，38，6： | 0 |
