M.H. Abdel-Aziz,E-S.Z. El-Ashtoukhy,M.Sh. Zoromba,M. Bassyouni,G.H. Sedahmed 한국공업화학회 2020 Journal of Industrial and Engineering Chemistry Vol.82 No.-
In this work, removal of nitrates by electrocoagulation in a batch electrochemical cell with horizontallyoriented electrodes was studied, the anode was a horizontal Al serpentine tube whose inner surface canpotentially act as a built-in cooler to control the cell temperature, a H2 evolving Al plate cathode wasplaced beneath the anode at the cell bottom where the stirring action of H2 bubbles improve the mixingconditions at the anode. The effect of operating parameters, such as initial NO3 concentration, initial pHof the solution, applied current density, and NaCl concentration on the removal efficiency wasinvestigated. The electrical energy consumption of the cell was calculated at different operatingparameters in order to optimize the operating conditions. The removal efficiency of the cell reached 100%after 100 min. A kinetic model for the process was proposed and verified by the experimental data. Themerits of the present new cell which is self-stirred and contains a built-in heat transfer facility fortemperature control were highlighted. Importance of the present work for agriculture drainage waterand underground water remediation was pointed out.
