separation factor
Separation coefficient
Separation coefficient is an important coefficient used to predict the fraction of an analyte that would be present in a given phase of a two-phase system. Separation coefficients are generally determined through chromatographic, but they can also be used to indicate the d......
pressure leaching
Leaching is a process by which metals are extracted from their ores using a liquid solvent. In the process of leaching, the ore is placed in a vessel with a liquid solvent and the particles of the ore dissolve in the solvent. The resulting solution, containing dissolved metals, is called a leachat......
Application Status of Nano Nickel Oxide
Application of nanometer oxidation nickel
Nanometer oxidation nickel has obtained wide application with its particular properties, such as good catalytic activity, mechanical strength and electrical conductivity. Compared with conventional catalysts, it can improve the catalytic activity, selecti......
stick medium
Molecular Sieving Membrane separation is an emerging membrane separation technology that can provide a unique way to separate, purify, and/or fractionate various gaseous and liquid components. Molecular sieving membranes are porous membranes with a pore size in the nanometer range and they act as ......
Platinum Group Metal Catalysts
Platinum Group Metals (PGMs) are a group of transition metals and are found in the platinum family located in the periodic table. They include: platinum, palladium, rhodium, ruthenium, iridium, and osmium. These metals have a variety of characteristics that make them desirable for catalytic applic......
Vanadium in rare refractory metal materials
Vanadium in Rare High Melting Point Metals
Vanadium, symbol V, has the atomic number 23 on the Periodic Table of Elements. It is a silvery-grey metal with a melting point of 1,926° Celsius (3,499° Fahrenheit).[1] Its majority use is in the production of steel alloys, but it is also present in o......
Rare earth element solvent extraction
Rare Earth Elements Solvent Extraction
Rare Earth Elements (REEs) are elements found within the Earths crust and have been primarily used as catalysts, colorants and phosphors in commercial applications. However, they have been gaining increasing attention due to their critical role in green and c......
