extraction de nickel-cadmium

Extraction du nickel — Wikipédia

Production de nickel en 2005 représentée en pourcentage du plus grand producteur : la Russie avec 300 000 tonnes par an.. La métallurgie extractive du nickel est l'ensemble des opérations permettant la fabrication de nickel métallique à partir du minerai.Elle concerne aussi le recyclage des déchets métallurgiques recyclés contenant du nickel (40 % du nickel consommé en 2005 …

Phyto-extraction of zinc, lead, nickel, and cadmium from …

With respect to the aforementioned discussions, in the present study, the phyto-extraction and recovery of zinc, lead, nickel, and cadmium from ZLR—as a metallurgical waste—have been investigated. A. retroflexus was used for uptake and extraction of heavy metals. Also, the effect of two concentrations of citric acid (0.005 and 0.1 M)—as a ...

Solvent extraction of copper, zinc, cadmium and nickel …

Further, extraction of zinc, nickel and cadmium was carried out using Cyanex 302. It was found that complete extraction of cadmium and zinc was taken place simultaneously using 2.5% Cyanex at eq. pH 2.1 leaving nickel in the aqueous raffinate, moreover Zn and Cd was selectively stripped out using 10% H2SO4 and 10% HCl, respectively.

Cadmium

Le cadmium est essentiellement un sous-produit de l'extraction, de la fonte et de l'affinage du zinc et, dans une moindre mesure, un sous-produit de la fabrication de plomb et de cuivre. L'essentiel du cadmium obtenu est utilisé dans la …

A bulk extraction method to determine the stable isotope …

The oceanic trace metals iron (Fe), nickel (Ni), copper (Cu), zinc (Zn), and cadmium (Cd) are crucial to marine phytoplankton growth and global carbon cycle, and the analysis of their stable isotopes can provide valuable insights into their biogeochemical cycles within the ocean. However, the simultaneous isotopic analysis of multiple elements present in seawater is …

Phyto-extraction of zinc, lead, nickel, and cadmium from …

In the case that the plants grew in the pots containing 25 wt% ZLR, the BCF of A. retroflexus for zinc, lead, nickel, and cadmium extraction were determined to be 0.3452, 0.1797, 0.7268, and 1.7360, respectively. The results were greater than the ones for the pots with the other ZLR percentages. Thus, 25 wt% ZLR was selected as the optimum ...

New method for recovery of nickel and cadmium from the …

A high cadmium extraction 99% was observed in the ratio of aqueous to organic phase 1.5 [13]. Extraction of Zn(II) and Cd(II) was presented with Cyphos IL 104 [trihexyl(tetradecyl)phosphonium bis (2,4,4-trimethylpentyl)phosphinate] diluted in toluene [14]. The pH, extractant concentration, temperature and equilibrium time have been evaluated.
