Instantaneous Generation of Sodium Hypochlorite Disinfectant by Electro Chemical Method

Abstract

Sodium hypochlorite which is produced using salt and raw water by electrochemical method. Low concentration sodium hypochlorite is been produced with electrodes like mixed metal oxides and titanium and optimization studies were done on these electrodes with different parameters. The foremost aim of present work is to compare and analysis the performance of various mixed metal oxide for production of sodium hypochlorite. The Ti/IrO2-SnO2-Sb2O5 electrode shows the cost effective and higher production. The physicochemical and electrochemical properties as well as the hypochlorite performances of the electrodes were inspected. Result shows the recyclability of Ti/IrO2-SnO2-Sb2O5 electrode shows 5 times and the concentration of sodium hypochlorite does not decrease as much low compared with other electrode. The phase composition and morphology in these products are characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM). Energy consumption is calculated based on production of sodium hypochlorite. The cost of sodium hypochlorite produced from Ti/IrO2-SnO2-Sb2O5 electrode is 0.019 ₹/L while the market price is 1.2 ₹/L with the concentration of 1%.
