Shop bis(2,4,4-trimethylpentyl) phosphinic acid-Detailed Image 2

■ Uses:

AD-290 has proven to be an excellent extractant for the separation of cobalt from nickel from both sulfate and chloride media.

Since the active component of SN272 extractant is a phosphinic acid, metals are extracted through a cation exchange mechanism. a variety of other cations can be extracted by SN272 extractant depending upon the solution pH. As a result, SN272 can not only be used for the separation of cobalt from nickel, but also for the separation of rare earths, and the extraction of Ga, In, Mo, Ge, Zr, etc.

SN272 extractant is totally miscible with common aromatic and aliphatic diluents, and is extremely stable to heat, acid and alkalis.

■ Package: 180k g / plastic drum ,900kg/IBC drum.

■ Storage: Avoid impact, water and fire. Keep cool, dry and ventilative.
