Lee, SC Ahn, BS Lee, WK 2024-01-21T19:34:01Z 2024-01-21T19:34:01Z 2021-09-01 1996-06-12 0376-7388 https://pubs.kist.re.kr/handle/201004/144416 A general physical model of a typical batch extraction system employing an emulsion liquid membrane process for the extraction of silver has been developed. The model takes into account the extraction reaction between the silver ion and the carrier molecules at the external interface, the diffusion of the complex in the membrane phase, the stripping reaction at the internal interface and the reaction of silver ion with the reagent, HCl, in the internal phase to yield silver chloride incapable of permeating through the membrane phase. In addition, the leakage of the internal aqueous phase to the external aqueous phase due to membrane breakage has been incorporated in this model, The batch extraction of silver using D2EHPA as a carrier has been carried out under various experimental conditions, The experimental data can be well explained by the present model.
