Fe₃O₄-Functionalized Boron Nitride Nanosheets as Novel Adsorbents for Removal of Arsenic(III) from Contaminated Water.

ABSTRACT: We report the application of Fe₃O₄-functionalized boron nitride nanosheets (BNNS-Fe₃O₄ nanocomposite) for the remediation of As(III) ions from contaminated water. The specific surface area of the nanocomposite has been found as 179.5 m² g^-1. Due to its superparamagnetic nature at room temperature, the nanocomposite can be easily isolated from the solution under an external magnetic field. For As(III) ions, the maximum adsorption capacity of the nanocomposite is obtained as 30.3 mg g^-1, which is approximately 4 times more than that of the bare BNNSs (8.5 mg g^-1). The results from density functional theory calculations are also in close agreement with experimental findings and show that As(OH)₃
