Triamidoamine Complexes of Chromium(III) and Chromium(IV)

Inorganic Chemistry, 2001
Treatment of [CrCl3(THF)3] with slightly more than 1 equiv of Li3(N3N) [(N3N)(3-) = ((Me3SiNCH2CH2)3N)(3-)] affords the triamidoamine complex [Cr(N3N)] (1) in 75% yield. 1 is oxidized by PhICl2, CuCl2, or AgCl to give the chromium(IV) complex [Cr(N3N)Cl] (2) in moderate yields.

Chromium in the elderly

Biological Trace Element Research, 1992
Several studies indicate that glucose tolerance improves and lipid levels decline in the elderly after supplementation with Cr-rich brewer's yeast or inorganic Cr. Other studies report equivocal results or no changes. Interpretation of these investigations is hampered by 1. Lack of a marker to identify Cr-deficient people 2.

Chromium Isotopes and the Fate of Hexavalent Chromium in the Environment

Science, 2002
Measurements of chromium (Cr) stable-isotope fractionation in laboratory experiments and natural waters show that lighter isotopes reacted preferentially during Cr(VI) reduction by magnetite and sediments. The 53 Cr/ 52 Cr ratio of the product was 3.4 ± 0.1 per mil less than that of the ...

Bioremediation of chromium solutions and chromium containing wastewaters

Critical Reviews in Microbiology, 2014
Cr(VI) represents a serious threat to human health, living resources and ecological system as it is persistent, carcinogenic and toxic, whereas, Cr(III), another stable oxidation state of Cr, is less toxic and can be readily precipitated out of solution. The conventional methods of Cr(VI) removal from wastewaters comprise of chemical reduction followed

Absorption and excretion of chromium from orally administered chromium chloride, chromium acetate and chromium oxide in rats

Trace Elements and Electrolytes, 2003
There is a growing interest in the absorption of different forms of trivalent chromium. In the current study, we evaluated the absorption and excretion of chromium after single-dose administration of 3 chromium compounds (chromium chloride hexahydrate, chromium oxide and chromium acetate hydroxide), compared to a control, in male Sprague Dawley rats ...

CHROMIUM AS A SUPPLEMENT

Annual Review of Nutrition, 1999
▪ Abstract  Chromium (Cr) is an essential mineral element that has received considerable public attention. The suggestion that Cr intake is generally low has generated interest regarding the purported beneficial effects of Cr supplementation on biological function and health of animals and humans.
