SUMMARY:

Oxidation of organic contaminants via sulfate radicals electrogenerated with boron-doped diamond electrode is an efficient electrochemical technique that is gaining more and more space and applications in the research field. The present work consists of the use of BDD electrodes, of different sizes and properties, for the production of persulfate during electrosynthesis. One of the stages of the research was the analysis of persulfate, before its application in organic compounds, with the objective of studying the oxidant's half-life and its potential for storage / storage, under different conditions, and with that define how many days the persulfate maintains the ability to oxidize selected organic compounds. The compounds chosen were methyl orange and pquinone, to which were added the electrogenerated persulfate solutions that were stored. The degradation of these compounds was accompanied by the use of a BDD sensor during electroanalysis.
