Abstract
Mechanistic studies including equilibrium and kinetic aspects of palladium extraction from acidic chloride media with 2-hydroxy-5-nonylbenzophenone oxime (LIX 65N) in chloroform solution are reported. The extracted species was established to be PdL, and the extraction equilibrium constant K Tor the reaction: Pd2+2HL(o)2PdL2(o)+2H+ was found to be 10 16.30The homogeneous chemical reaction PdCl3+HLPdCl2-LminusH+ Clminus was established as The rate-determining step of the overall.reaction having a rate constant of 3.74x10 M-1s.Keywords
