Capture of iodide from wastewater by effective adsorptive membrane synthesized from MIL-125-NH2 and cross-linked chitosan

The mainly nuclear waste is radioactive iodine (I-129 or I-131) so its disposal have great significance to produce safe water. Porous metal-organic works (MOFs) have awesome potential as high-effective adsorbents for water treatment. In any case, destitute separation limits their viable application. All in all, we worked on the development of MOFs with cross linked chitosan as a promising adsorbent material for the remediation of environmental water polluted by iodine. Due to the drawbacks of current adsorbents such as low uptake capacity, high cost, and non-recyclability; a novel cross-linked chitosan-MOF composite was synthesized and used in the adsorptive removal of iodine from wastewater. The novel composite shows high iodine removal capacity 399.68 mg g(-1) at room temperature. The cross-linked chitosan-MOF composite shows chemical and thermal stability, high removal efficiency for capture of iodine from wastewater and furthermore good recyclability.
