摘要：
Impregnated resins containing Alamine 336 were prepared by direct adsorption of the extractant onto Amberlite XAD2 and physico-chemical characterization was performed. The kinetic and equilibrium extraction of Pd(II) from hydrochloric acid media as well as Pd(II) loading isotherms are reported. Pd(II) extraction by resins containing Alamine 336 could be explained by the formation of (R3NH+)(2)PdCl4-2 complexes in the resin phase. (C) 1998 Elsevier Science B.V. All rights reserved.
