Ion exchange based approach for rapid and selective Pb(II) removal using iron oxide decorated metal organic framework hybrid

Polyacrylic acid capped Fe3O4 – Cu-MOF (i-MOF) hybrid was prepared for rapid and selective lead removal, with 93% removal efficiency, exceptional selectivity, and adsorption capacity of 610 mg/g and 91% of i-MOF hybrid could be easily separated from the contaminated water using magnetic separation. The adsorption process followed a pseudo-second-order model and the adsorption efficiency decreased from 93% to 83% on raising the temperature from...
