Catalytic reductive dehalogenation of hexachloroethane (HCE) was shown to be possible using a graphite electrode coated with a film of the poly(ester sulfonic acid) containing myoglobin (Mb). The effectiveness of the dehalogenation was limited by the solubility of HCE in aqueous solutions. In order to produce an electrode that could dehalogenate HCE in non-aqueous solutions, Mb was chemically modified by addition of poly(ethylene oxide) (PEO). The PEO-Mb/AQ29D modified electrode was found to be suitable for the reductive dehaolgenation the HCE in ethanolic solutions. The catalytic response was shown to be linearly dependent on the bulk concentration of HCE.
