Synthesis of amino functionalized magnetic graphenes composite material and its application to remove Cr(VI), Pb(II), Hg(II), Cd(II) and Ni(II) from contaminated water.
TL;DR: It was found that the metals sorption was accomplished mainly via chelation or ion exchange, and the results of thermodynamic studies illustrate that the adsorption process was endothermic and spontaneous in nature.
