Product details

Solvent Extraction Reagent


Description

Eagles 84-I solvent extraction reagent is water insoluble 2-hydroxy-5-nonylaceto-phenone oxime in a high flash point hydrocarbon diluent.


Principal uses

Eagles 84-I forms water insoluble complexes with various metallic cations in a manner similar to that shown below for copper:

2RH(org) + Cu+2(aq)  ⇌  R2Cu(org) + 2H+(aq)

Copper extraction from typical leach solutions is pH dependent. Stripping is accomplished with acid solutions such as a typical barren electrolyte from copper electrowinning.
