SUMMARY:

Waste generation and the exorbitant amount of water produced from oil production and extraction activities are undoubtedly one of the biggest challenges for the oil industry, in which they need to comply with the established toxicity limits for their correct disposal. Even though the inspection bodies act, much has been seen regarding the growing contamination of ecosystems and this fact has drawn the attention of scientists in search of the use of technologies and studies aimed at remediating soils and decontaminating waters. In this context, the present work aimed to investigate the ex-situ oxidative capacity of electrochemically generated persulfate against sandy soil enriched with phenanthrene and a real sample of produced water. The results were quite promising in which the removal of phenanthrene in the soil was almost 80%. As for the use of persulfate in a real sample of produced water that has an extremely complex matrix, a mineralization rate of up to 58% was obtained, also observing the formation of carboxylic acids that have a wide use and importance for the industry. In general, it can be inferred that the ex-situ use of persulfate against different pollutants and concentrations was viable in the oxidation process and favored the conversion of pollutants into value-added products.
