Removal of Hexavalent Chromium from Electroplating Wastewater by Electrocoagulation with Iron Electrodes
The performance of electrocoagulation using iron electrodes for the removal of hexavalent chromium from synthetic aqueous solutions and actual industrial electroplating wastewater was studied. Parameters affecting the electrocoagulation process, such as initial pH, applied current density, initial metal ion concentration, COD and time of electroprocessing were investigated. The optimum pH was f...
متن کاملHexavalent chromium removal from a simulated wastewater using Fe(II) modified bentonite
Background and Objective: Hexavalent chromium is reported to be highly toxic, mutagenic and carcinogenic; hence treatment of water and wastewater contaminated with this element by low-cost and environmentally friendly methods is of great importance. Therefore the aim of present study was to evaluate the efficiency of Fe(II) modified bentonite for hexavalent chromium removal from a simulated was...
متن کاملOn the removal of hexavalent chromium from wastewater: a comparative study between photocatalytic and chemical reduction processes
Common sources of chromium in wastewater are electroplating and leather industries. Hexavalent chromium is more toxic and carcinogenic compared to its trivalent counterpart. Conversion of Cr (VI) to Cr (III) in an aqueous medium both by chemical reduction using zerovalent iron and by photocatalytic reduction using UV radiation and ZnO semiconductor has been investigated using potassium dichroma...
متن کاملRemoval of Hexavalent Chromium from Wastewater by Use of Scrap Iron
Hexavalent chromium is highly toxic to most living organisms and a known human carcinogen by the inhalation route of exposure. Therefore, treatment of Cr(VI) contaminated wastewater is essential before their discharge to the natural water bodies. Cr(VI) reduction to Cr(III) can be beneficial because a more mobile and more toxic chromium species is converted to a less mobile and less toxic form....

Publication 1. A. Manceau et al, “Quantitative Zn speciation in smelter-contaminated soils by EXAFS spectroscopy,” Am. J. Sci. (in press, 2000). Figure 3 (top) Soil samples were taken at several depths from a contaminated site. (bottom) Model compounds derived from polarized-EXAFS data at the ESRF and μ-EXAFS data at the ALS provide a good fit with powder-EXAFS spectra from a soil sample, there...
