PC-88A is a purified 2-ethylexyl hydrogen 2-ethylhexyl phosphonate, HEH(EHP).
Particularly, in the separation of cobalt from nickel, PC-88A is superior to D2EHPA.
PC-88A is an excellent reagent for the solvent extraction of various metals.
In addition, PC-88A is very suitable for use in the process of refining rare-earth metals. In
this use, PC-88A can reduce the cost of mineral acid in the back extraction, and in the
process that follows, PC-88A can also save the cost of alkali in neutralizing an acidic
PC-88A, which is not less than 95 percent in purity, is commercially produced and
offered to customers in large or small quantities.
