Encapsulation of starch hydrogel and doping nanomagnetite onto metal organic frameworks for efficient removal of fluvastatin antibiotic from water.
Growing interests and efforts have been recently focused on design and assembly of novel hydrogel nanosorbents for removal of drugs from wastewater. Therefore, this work is aimed to immobilize and encapsulate starch hydrogel matrix onto metal organic frameworks (MOFs) and dope with nanomagnetite. The magnetic MOFs Starch hydrogel (NFe3O4@Zn(GA)/Starch Hydrogel) was synthesized via microwave irradiation process and characterized with high surface area (528.39 m2/g) mesoporous with pore size 2.90 nm and highly crystalline structure. The maximum swelling ratio (1000.0 was optimized at pH 10, 180 min and 25 degC. The validity of NFe3O4@Zn(GA)/Starch Hydrogel for adsorptive removal of Fluvastatin statin drug provided maximum equilibrium adsorption capacity 782.05 mg g 1. The Langmuir isotherm and pseudo second kinetics models were correlated well with the computed correlation coefficient values 0.9991 and 0.9997, respectively. The validity of NFe3O4@Zn(GA)/Starch Hydrogel for removal of FLV statin drug from real water matrices was confirmed in the range 96.15 99.99
