Cobalt and nickel are then separated by elution with 70% acetone-30% 2 M hydrochloric acid; nickel is eluted before cobalt. The method can be applied to the determination of nickel and cobalt in materials with high iron content such as steels ; compleximetric titrations are used for the ...
Step-by-Step Solution:1. Identify the Metals: The question asks about iron, cobalt, and nickel. These are transition metals found in the d-block of the periodic table.2. Understand the Grouping</
aNickel, Raney nickel and cobalt are common electrode materials for being used in alkaline solution electrolytic baths because their price, corrosionresistance and chemical stability are at satisfactory levels 因为他们的价格、corrosionresistance和化学制品稳定在令人满意的水平,镍, Raney镍和钴是共同的电极材料...
Separation of cobalt(II) from nickel(II) by a hybrid liquid membrane-electrodialysis process using anion exchange carriers Cobalt and nickel are widely used in various branc Sadyrbaeva,T Zh. - 《Desalination the International Journal on the Science & Technology of Desalting & Water Purification》 ...
while the decarbonization of the transport sector can benefit from sustainable fuels such as electrofuels and biomethane8, battery technology, which depends fundamentally on critical materials such as lithium, cobalt, and nickel, is widely deemed indispensable in renewable energy storage and automobile el...

Since then, we have devoted ourselves to the development of ATH and AH of ketones with iron, cobalt, and nickel catalysts containing novel chiral aminophosphine ligands. In our study, the iron catalyst containing chiral aminophosphine ligands, which are expected to control the stereochemistry at ...
Compounds of chromium, nickel, cadmium, cobalt and arsenic are carcinogens to humans and/or experimental animals. In general, the carcinogenic potential of metals depends largely on oxidation state and solubility which affect the bioavai... A.,Hartwig,and,... - 《Toxicology Letters》 被引量: ...
The orientation and the axial, Δχax, and rhombic, Δχrh, components of the magnetic susceptibility tensor anisotropy for the cobalt(II) and nickel(II) derivatives of azurin from Pseudomonas aeruginosa have been determined from 1H NMR data. For both derivatives, the axial geometry of the syst...
These are excellent tools to cope with the broad concentration ranges of nickel and cobalt in biological and environmental materials, so that for nearly every task an appropriate and sometimes an additional reference method is used. The introduction of high-pressure or rather high-temperature ashing ...
