Js. Do et Wc. Yeh, IN-SITU PAIRED ELECTROOXIDATIVE DEGRADATION OF FORMALDEHYDE WITH ELECTROGENERATED HYDROGEN-PEROXIDE AND HYPOCHLORITE ION, Journal of Applied Electrochemistry, 28(7), 1998, pp. 703-710
Formaldehyde was degraded with hydrogen peroxide and hypochlorite ion
electrogenerated by paired electrolysis of dissolved oxygen and chlori
de ion in aqueous solution. Degradation of formaldehyde in the cathodi
c compartment was significantly affected by the ratio of electrolyte v
olume to cathodic surface area, oxygen sparging rate and stirring rate
. The model calculations correlated sufficiently well with the experim
ental results. The average current efficiency and degradation fraction
of the in situ paired electrooxidative degradation of formaldehyde we
re experimentally found to be 62.0% and 93.2%, respectively.
