Preparation and application synthesis of magnetic nanocomposite using waste toner for the removal of Cr(<scp>vi</scp>)

Abstract

A novel magnetic nanocomposite is prepared using waste toner <italic>via</italic> calcination in ammonia, which exhibits excellent magnetic properties and high efficiency for the removal of Cr(<sc>vi</sc>) <italic>via</italic> pH regulation using H₂SO₄.
