Preparation of CoFe2O4-CMC and its adsorption mechanism study toward Pb(II)

Year: 2024

Type: article

Abstract: The heavy metal Pb(II) is highly toxic, and it is very important for its separation and collection to improve water quality. To alleviate the phenomenon of agglomeration and inactivation, the highly dispersible composite materials (CoFe2O4-CMC) were prepared by modifying superparamagnetic CoFe2O4 using carboxymethyl cellulose (CMC) in this paper. The adsorption capacity of CoFe2O4-CMC0.5 for Pb(II) was 119.3 mg/g. Dynamic fitting results showed that the adsorption process included physical adsorption of intermolecular force and chemical adsorption of coordination. Compared with CoFe2O4, the addition of CMC improved the dispersion and adsorption performance, providing a new idea for environmental water quality remediation.
