Abstract: ABSTRACT OF THE DISCLOSURE      An  electrolytic  process  and  apparatus  is  disclosed  for oxidizing or reducing inorganic and organic species, especially in dilute aqueous solutions.  The electrolytic reactor includes an anode and cathode in contact with a packed bed of particulate ion exchange material which establishes an infinite number of transfer sites in the electrolyte to significantly increase the mobility of the ionic species to be oxidized or reduced toward the anode or cathode, respectively.  The ion exchange material is cationic for oxidation and anionic for reduction, or a combination of both for special circumstances.  Preferably, the ion exchange material is treated to convert a portion of the transfer sites to semiconductor junctions which act as mini anodes, or cathodes, to significantly increase the capacity of the reactor to oxidize or reduce the species to be treated.  Exemplary applications for the disclosed electrolytic process and apparatus are the conversion of halides to halous acids in dilute solutions.
