A Magnetic TiO2/PKSAC/Fe3O4 Composite with Enhanced Photocatalysis and Adsorption for the Concurrent Removal of Heavy Metals

An effective material to assist in the removal of heavy metal pollutants in the water system is necessary, as they persist for a long time and pose danger to the environment. A novel multifarious TiO2/PKSAC/Fe3O4 composite material with combined adsorption, photocatalytic and magnetic properties was...
