Download The Biological and Environmental Chemistry of Chromium. Comprehensive information for the element Chromium - Cr is provided this page including scores of properties, element names in many languages, most known nuclides and Chromium ! Introduction ! The biological effects of chromium strongly depend on its specific chemical form. Nutritive effects are exclusively related to chromium III (valence 3+), and all major toxic effects are associated with chromium VI (valence 6+) (Nielsen 1994; This article includes a survey of removal techniques for Cr(VI)-contaminated Slem, H., (1994) The Biological and Environmental Chemistry of Chromium, pp. PerspectiveENVIRONMENTAL CHEMISTRY the stable isotope technique reported Ellis et al.

Still it is difficult to find in one place enough details about its chemistry in relation to electrodeposition. An attempt is made to present its stereochemistry, electrochemistry, redox reactions and structure of polynuclear chromic acids, among Jump to Chemical properties of chromium - In the environment, chromium exists in several are +3 and +6, with different chemical and biological effects.
