Le cadmium est en solution (0,2 à 0,3 g de Cd/L) dans le bain d'électrolyse. Il est récupéré, après épuisement de Zn 2+, par cémentation à l'aide de zinc. On obtient des boues bleues contenant au moins environ 6 % de cadmium et 15 % de cuivre. Les autres poussières réutilisables sont …

Ontdekking. Cadmium werd in 1817 ontdekt door de Duitse chemicus Friedrich Strohmeyer als een onzuiverheid in het mineraal calamiet (zinkcarbonaat).Gedurende zo'n 100 jaar was Duitsland het enige land ter wereld dat op grote schaal cadmium produceerde.. Alhoewel vandaag de dag bekend is dat cadmium en cadmiumverbindingen uiterst giftig zijn, stelde de Britse Pharmaceutical Codex in 1907 …

Polished Cd is matted after a while, forming CdO [5]. At 300 °C Cd forms a thin brown gas-permeable coating. The yield increases parabolic with temperature [5]. Cadmium metal burns in air to form cadmium(II)oxide. The burning temperature is above the sublimations temperature of CdO, 1385 °C [5]. 2 Cd (s) + O 2 (g) 2 CdO (s)

Intake of toxic cadmium (Cd) from rice caused Itai-itai disease in the past and it is still a threat for human health. Therefore, control of the accumulation of Cd from soil is an important food-safety issue, but the molecular mechanism for the control is unknown. Herein, we report a gene (OsHMA3) r …

Cadmium is a natural element in the earth's crust. It is usually found as a mineral combined with other elements such as oxygen (cadmium oxide), chlorine (cadmium chloride), or sulfur (cadmium sulfate, cadmium sulfide).All soils and rocks, including coal and mineral fertilizers, contain some cadmium.Most cadmium used in the United States is extracted during the production of other metals like ...

Cadmium (Cd) is a toxic non-essential transition metal that poses a health risk for both humans and animals.

About three-fourths of cadmium is used in Ni-Cd batteries, most of the remaining one-fourth is used mainly for pigments, coatings and plating, and as stabilizers for plastics. Cadium has been used particularly to electroplate steel where a film of cadmium only 0.05 mm thick will provide complete protection against the sea.

Cadmium (selten auch Kadmium; von altgriechisch καδμία kadmía, lateinisch cadmia und cadmea „Galmei") ist ein chemisches Element mit dem Elementsymbol Cd und der Ordnungszahl 48. Es wird meist zu den Übergangsmetallen gezählt, obwohl es eine abgeschlossene d-Schale besitzt und damit eher den Hauptgruppenelementen, vor allem den Erdalkalimetallen ähnelt.

Cadmium is a chemical element with the symbol Cd and atomic number 48. This soft, silvery-white metal is chemically similar to the two other stable metals in group 12, zinc and mercury.Like zinc, it demonstrates oxidation state +2 in most of its compounds, and like mercury, it has a lower melting point than the transition metals in groups 3 through 11.

Abstract. BACKGROUND: The pathogenesis of itai-itai disease continues to be controversial, although cadmium (Cd) poisoning which arises via polluted water and rice in Japan is likely involved. Until recently, however, a well-defined animal model for Cd intoxication was not available. An animal model for itai-itai disease was produced in rats by low-dose Cd treatment, intraperitoneally for a ...
