Regeneration and recycling of waste Fe(III)/Cr(III) hydroxide for the continuous adsorption of Ni(II) and Cr(VI)
The waste Fe(III)/Cr(III) hydroxide is recycled after alternating adsorption and desorption of Ni(II) and Cr(VI). Six regeneration cycles have been observed without any significant loss in metal removal efficiency of the adsorbent.
