Abstract
Processes and apparatuses are described for recovering components dispersed in an aqueous solution comprising contacting said solution as a first solution with an electrically conducting barrier, diaphragm or membrane which has a high affinity for at least one of said components whereby a substantial fraction of said component is sorbed by said barrier. The barrier is subsequently contacted with a second aqueous solution and a direct electric current is passed through said barrier and second solution in a direction substantially parallel to the smallest dimension of the barrier thereby facilitating desorption of at least one of the sorbed components from the barrier into the second solution which solution is thereafter removed.
