| Sumario: | The electro-Fenton process is an electrochemical method for waste water treatment based on the production of hydroxyl radicals via H2O2 generation in the presence of ferrous ions. The aim of this work is of applied Electro-Fenton technique to incinerate lubricate additive biocide N,N-methylenebismorpholine (C9H18N2O2).the effect of some operational parameters such as applied cathodic potential, the electrolysis time and aeration,concentration of supporting electrolyte on the generation of H2O2 was investigated. The optimal cathodic potential on the generation of H2O2 production was -500mV/SCE corresponding to a density current of 1.4 mA/cm², the production of hydrogen peroxide with the aeration and electrolysis time, then became stationary after 2h of electrolysis, the low pH favorite production of H2O2 electro generated. Whereas the Concentrations of supporting electrolyte of the solution have a slight affect. The degradation and incineration of N,N-methylenebismorpholine in the optimized parameters was also investigated (potential, current density, COD/Fe²+ ratio ) the result indicates that 97% of COD was incinerated at 50mA and the optimal concentration of catalyst is between 28 and 58mg/l. |
