XPS confirmed such nanoparticles as containing Cu°, with the Cu removal mechanism therefore likely via cementation with Fe°. Overall the results demonstrate nZVI as effective for the one-pot and selective formation of Cu°-bearing nanoparticles from acidic wastewater, with the technique therefore potentially highly useful for the selective upcycling of dissolved Cu in wastewater into high value nanomaterials.

Treatment of Acid Mine Drainage using Magnesium Hydroxide

pH cannot be raised sufficiently. There are two mechanisms operating when metal containing acid water is neutralized with Mg(OH)2. The first mechanism is where metals are precipitated at metal hydroxides. The second mechanism is where metals are absorbed onto the surface of Mg(OH)2 particles. Teringo (1987) found that with Mg(OH)2, metals can
