Reactivity of nano zero-valent iron in permeable reactive barriers

Polish Journal of Chemical Technology, 2015
Abstract In this paper, the ability of nZVI to remove heavy metals (Cd, Cu, Ni, Pb, Zn) from multicomponent aqueous solutions was investigated through batch experiments. The experimental data were fitted to a second-order kinetic model based on solid capacity. The data for copper and lead fitted well into the second-order kinetic model,
