WebApr 13, 2024 · A diaphragm is introduced to separate the anode and cathode reactions to prevent the cathode product (NaOH) and the anode product (Cl 2) from crossing over to generate sodium hypochlorite. The negatively charged membrane can inhibit the back diffusion of OH − [ 7 ]. WebOur customers depend on Hawkins for high quality products, a consistent and cost-effective supply of Sodium Hydroxide. Hawkins has a team dedicated to ensuring the quality of the Sodium Hydroxide we supply. Caustic soda is most commonly manufactured by the electrolysis of sodium chloride brine in either a membrane or diaphragm electrolytic cell.

WebSome chloride ions also migrate across the diaphragm resulting in the cell liquor containing about 16% sodium chloride. The cell liquor is typically concentrated to 50% sodium hydroxide by an evaporation process. The salt recovered in the evaporation process is returned to the brine system for reuse. Membrane Cell Technology Webdiaphragm cell or mercury cell process. Therefore, these will be the only 2 processes discussed in this section. 8.11.2.1 Diaphragm Cell - Figure 8.11-1 shows a simplified block diagram of the diaphragm cell process. Water (H2O) and sodium chloride (NaCl) are combined to create the starting brine solution. The brine undergoes
WebDiaphragm cell electrolysis (bipolar) In diaphragm cell electrolysis, an asbestos (or polymer-fiber) diaphragm separates a cathode and an anode, preventing the chlorine forming at the anode from re-mixing with the sodium hydroxide and the hydrogen formed at the cathode. This technology was also developed at the end of the nineteenth century.
