Preparation of core-shell magnetic Fe3O4@SiO2-dithiocarbamate nanoparticle and its application for the Ni2+, Cu2+ removal

A typical superparamagnetic nanoparticles-based dithiocarbamate absorbent (Fe3O4@SiO2-DTC) with core-shell structure was applied for aqueous solution heavy metal ions Ni2+, Cu2+ removal.
