Membrane extraction and Electrodeposition of silver(I) in systems with di(2-ethylhexyl) hydrogen phosphate

Extraction of silver(I) from nitric acid solution by electrodialysis with liquid membranes containing di(2-ethylhexyl) hydrogen phosphate with addition of tri-n-octylamine in 1,2-dichloroethane is studied. The effects of the composition of aqueous solutions and liquid membranes as well as of the basic parameters of electrodialysis on the Ag(I) transport and electrodeposition rates are examined, and the process conditions are optimized.
