Properties and Usage:
Bis(2,4,4-trimethylpentyl)phosphinic Acid is an acidic phosphinic acid extractant with excellent metal separation performance. It was originally designed for the separation of nickel and cobalt, but due to its excellent extraction effect, it has been widely used in the separation process of other metal systems.
What is unique about this product is that its active ingredient is organic phosphonic acid, which achieves efficient extraction of metals through a cation exchange mechanism. In the presence of nickel, highly selective extraction of cobalt can be achieved, while other metal ions can also be extracted under different solution pH values. In addition, Bis(2,4,4-trimethylpentyl)phosphinic Acid also has good stability and shows excellent heat resistance, acid resistance and alkali resistance in aromatic or aliphatic diluents.
The properties of the product make it not only suitable for the separation of nickel and cobalt, but also can be widely used in the extraction and separation process of rare earth elements, gallium, indium, molybdenum, germanium, zirconium and other metals.
Perfect for the metal industry, Fscichem 83411-71-6 can replace Cyanex 272
