Abstract
Section titled “Abstract”Abstract The electrochemical synthesis of peroxodicarbonate was performed on boron‐doped DIACHEM ® diamond anodes (BDD). The influence of various parameters was studied and promising conditions were determined in an undivided cell design by CONDIAS GmbH. The best performance was obtained with a temperature below room temperature (<18 °C), high current density (720 mA cm −2 ), high flow velocity (170 cm s −1 ) and starting concentration close to the maximum solubility of sodium carbonate (1.5 M Na‐carbonate). A high concentration of peroxodicarbonate of 282 mM was obtained with highest current efficiency of about 76%. Future industrial applications appear to be promising. Experiments performed to investigate the bleaching power of the peroxodicarbonate gave promising results. Additionally, a new type of DIACHEM ® diamond electrode based on Molybdenum substrate was successfully tested.
