Chromium (vi) Compounds
Chromium (VI), also known as hexavalent chromium, is the second most stable oxidation state of chromium. Rarely occurring naturally, most chromium (VI) compounds are manufactured (products or by-products). Chromium (VI) can be reduced to the more stable chromium (III) in the presence of reducing agents (e.g. iron) or oxidizable organic matter (OSHA, 2006). Selected chemical and physical propert...

متن کامل[Occupational exposure to chromium(VI) compounds].
This article discusses the effect of chromium(VI) (Cr(VI)) on human health under conditions of acute and chronic exposure in the workplace. Chromium(VI) compounds as carcinogens and/or mutagens pose a direct danger to people exposed to them. If carcinogens cannot be eliminated from the work and living environments, their exposure should be reduced to a minimum. In the European Union the propose...
متن کاملSorption of Chromium (VI) from an Aqueous Solution by a New Polymeric Resin Prepared by Gamma Radiation
A new polymeric resin poly(maleic acid –acrylamide )-Cesium P(MA-AM)-Cs was prepared by gamma radiation-induced co-polymerization of maleic acid ( MA) with acrylamide (AM) in the presence of cesium chloride CsCl as a metal salt in aqueous solution route at 25 KGy to be used as a sorbent. The polymeric resin was characterized using Fourier transform infra-red spectroscopy (FTIR), simultaneous th...
متن کاملAnion-exchange Properties of Hydrotalcite-like Compounds
-Ion-exchange isotherms between hydrotalcite-like compounds (HT) of the NO3-, CI-, and SO4forms and F , 0% Br , I , OH-, SO42-, CO3 z-, and Naphthol Yellow S (NYS 2-) ions were determined, and the spacing and the width of the 003 reflection were measured as a function of HT composition. The ion-exchange equilibrium constant for HTs of monovalent anions are in the sequence OH> F > Cl > Br> NO3> ...
