In the form of vitamin B 12, cobalt plays a number of crucial roles in many biological functions.However, recent studies have provided information on the biochemistry and bioinorganic chemistry of several proteins containing cobalt in a form other than that in the corrin ring of vitamin B 12.To date, eight noncorrin-cobalt-containing enzymes …

McCabe–Thiele diagrams were constructed to determine the theoretical extraction and stripping stages and a flowsheet to separate cobalt and zinc from nickel was proposed. With this flowsheet, more than 99% cobalt and zinc could be separated, resulting in a pure nickel solution with less than 10 mg L −1 of cobalt and zinc.

This study aims to develop a process for separating magnesium from nickel and cobalt pregnant leach solutions, overcoming the limitations of conventional metal separation techniques. The process utilizes ethylenediaminetetraacetic acid (EDTA) for complexation, selectively binding with nickel and cobalt to reduce their coprecipitation …

It is very important to separate and recover cobalt from nickel smelting since cobalt resources are scarce. At present, the separation methods of nickel and cobalt …

The competitive performance and selectivity for the separation of Co2+ and Ni2+ from Mn2+ solution by a triethylene–tetramine-modified cross-linked chitosan …

With this flowsheet, more than 99% cobalt and zinc could be separated, resulting in a pure nickel solution with less than 10 mg L −1 of cobalt and zinc. CONCLUSIONS: The current study shows that Cyanex 272 can be used to separate cobalt and zinc in one Cyanex 272 circuit effectively from concentrated nickel solutions to obtain …

The rising demand of metals for batteries is calling for advanced methods to separate metallic mixtures in mineral ores and electronic waste. In particular, the extraction in separate form of nickel and cobalt are focusing attention because these metals are used in cathodes of lithium-ion batteries. Here we developed the selective separation of …

3.4.3. Ion Exchange Chromatography. In ion exchange chromatography, the support consists of tiny beads to which are attached chemicals possessing a charge. Each charged molecule has a counter-ion. The figure shows the beads (blue) with negatively charged groups (red) attached. In this example, the counter-ion is sodium, which is positively …

Physical Properties. Cobalt is a sturdy, gray metal which resembles iron and nickel. Although cobalt is ductile it is also somewhat malleable. Ductile means the metals ability to be drawn into thin wires. Malleable means is …

The demand for lithium-ion batteries (LiBs) is significantly increasing leading to a shortage in supply for critical metals, such as lithium and cobalt. Recycling LiCoO2 cathodes can provide a secondary source for these critical metals, which are necessary raw materials for the synthesis of modern LiB cathodes, such as nickel manganese cobalt …

Biochemistry Free & Easy (Ahern and Rajagopal) 9: Techniques 9.7: Histidine Tagging ...
