Production of Sodium Hypochlorite by Electrochemical Methods: Development of New Generation Electrodes

In the denim sector, the difficulty in the supply of sodium hypochlorite used in the washing processes where bleaching and bleaching processes are carried out and the hydrogen peroxide chemicals required for neutralization have become an important problem in the global market and their costs have increased. In addition, green chemistry and sustainable synthesis reactions are attracting attention in today's world where environmental concerns have reached the highest level. Electrochemical techniques, one of them, are generally used in treatment and disinfectant production. Industrially, the synthesis of sodium hypochlorite is carried out with chemicals and processes that are harmful to the environment. In this study, the synthesis of sodium hypochlorite, which is a bleaching and bleaching chemical used in various fields in denim production lines, as a cost-effective, environmentally friendly and sustainable green chemistry was carried out using electrochemical techniques with brine.  Thanks to the new generation electrode and electrochemical cell design prepared using Mn (III) imprinted 402 grade steel, sodium hypochlorite production efficiency was improved by 40%. The bleaching and effecting results were compared with the conventional ones and found to be more effective.
