Abstract
Cyanides are potential pollutants even in traces and regulations limiting the cyanide
concentration in industrial effluents down at 0.2 pprn and the permissible tolerance for
inland surface waters at 0.01 Dpm have been specified. Several investigations on the
electrooxidation of cyanide in the effluent have been reported in literature Use of three
dimensional electrodes has been the recent development in this area of research.
In the present paper, a comparison of packed bed electrode cells of different configurations
has been made for the anodic oxidation of cyanide. The initial concentration of electrolyte
has been maintained at cyanide 200 pprn and NaCl 5 gpl. It has been observed that the
packed bed cells of flow-bypassconfiguration function better than the flow through cells
