Magnetic Metal Organic Framework Immobilized Laccase for Wastewater Decolorization

The laccase enzyme was successfully immobilized over a magnetic amino-functionalized metal–organic framework Fe3O4-NH2@MIL-101(Cr). Different techniques were used for the characterization of synthesized materials. Fe3O4-NH2@MIL-101(Cr) showed excellent resistance to high temperatures and low pH levels with immobilization capacity large activity recovery, due combination covalent binding adsorption advantages. long-term storage 28 days indicated retention 88% its initial activity, stability system. Furthermore, residual 49% observed at 85 °C. effectively biodegradation Reactive Black 5 (RB) Alizarin Red S (AR) dyes in water. factors affecting RB AR degradation using (dye concentration, temperature pH) investigated determine optimum treatment conditions. conditions dye removal mg/L 25 °C, 4. At conditions, sorption-synergistic mechanism system caused total 81% RB. Interestingly, reusability study this up five cycles ability reuse it several times water treatment.
