  • Title: Enhanced electro-catalytic degradation of chloroorganic compounds in the presence of ultrasound.
    Author: Yasman Y, Bulatov V, Rabin I, Binetti M, Schechter I.
    Journal: Ultrason Sonochem; 2006 Apr; 13(3):271-7. PubMed ID: 15975844.
    Abstract:
    The application of finely divided (black) Pd and Pd-Fe powder in the sono-electro-catalytic reduction of chlorophenoxy herbicides (2,4-D) and chlorophenols (2,4-DCP) in aqueous solutions allows for effective destruction of toxic chlorinated aromatic compounds. At 20 degrees C complete conversion of these compounds is observed within 10 min. On bimetallic Pd/Fe catalyst, intermediates due to the oxidation reaction are detected in addition to the products of dechlorination. The bimetallic catalyst appears to be energetically and economically superior to the Pd. In both cases, the reaction times were considerably shortened in comparison with traditional electro-catalytic processes.
