GO/Fe3O4/PEI nanocomposites were prepared by chemical strategy, they show enhanced adsorption performance for Cu2+ due to the extraordinary complex ability of PEI. Moreover, they can be easily separated due to the superparamagnetism of Fe3O4.
A novel, magnetic GO-modified with molecularly imprinted polymer (MGO@MIP) was controllably synthesized and shown to exhibit excellent adsorption performance towards PCP.
