Self-assembled magnetic bio-adsorbent from soluble starch, chitosan, and tannic acid for facilely recyclable and ultra-high capacity cationic dye removal from water.
Conventional biomass adsorbents often suffer from structural instability and difficult recovery. To address this, we report a novel strategy for fabricating a magnetic bio-adsorbent by harnessing the dual-role of tannic acid (TA) in a synergistic self-assembly process. The key novelty lies in using TA to first drive th...
