    Abstract: Chromium can be recovered by electrodeposition from tanning wastewater because of the presence of high chromium concentration, sodium chloride and formate salt in the solution. Chromium coatings were prepared by adjusting current density and pH through electro-deposition in simulated tanning wastewater. The polarization behavior of chromium deposition was explored by the polarization curves. The results showed that when pH was 2.8 and the current density was 60 A·dm-2, the optimal deposition occurred. The surface morphology, element composition and element valence of the coatings were investigated by scanning electron microscopy (SEM), energy dispersive spectrometey (EDS) and X-ray photoelectron spectroscopy (XPS), respectively. The chromium coatings deposited from the electrolyte mainly contained metallic chromium, oxidized chromium and chromium hydroxide. This research has provided a new method for the recovery of Cr from wastewater.
