Study on synthesis of MnFe2O4/GNPs composite and application on heavy metal removal

In this paper, the MnFe2O4/GNPs composite was synthesized by hydrothermal method, in which the mixed-oxide particles were formed in-situ onto the GNPs surface. The purpose of this method is to distribute evenly and avoid the agglomeration of oxide particles, thus increase the surface area so the absorprion process is more effective.
