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.

A method of recovering biospecifically, sorbable components dispersed in a aqueous solution comprising: (a) contacting said solution as a first solution with an electrolytically conducting barrier having biospecific sorbing properties for at least one of said components whereby a substantial fraction of said components in said solution having biospecific binding affinity for said barrier is sorbed by said barrier, said barrier supported by and in juxtaposition with an electrolytically conducting membrane thereby forming a composite membrane-barrier pair; (b) removing said first solution from contact with the said barrier; (c) contacting said barrier with a second aqueous solution; (d) passing a direct electric current through said membrane-barrier pair and said second solution in a direction approximately parallel to the smallest dimension of said membrane-barrier pair thereby facilitating the desorption of at least one of said components having biospecific binding affinity for the said barrier into said second solution; and (e) removing said second solution from contact with said barrier.
