APPLICATION OF ACTIVATED PERSULFATE PROCESSES FOR THE TREATMENT OF WATER AND HIGH-STRENGTH WASTEWATER
Kattel, Eneliis, Ph.D. thesis, Tallinn University of Technology, Estonia. 105 pp, 2018
Persulfate is a strong and stable oxidant that needs extra activation to generate sulfate radicals that reduce organic pollution. The productivity of sulfate radicals from persulfate can be influenced by the type of activation employed, e.g., metallic ions, heat, radiation, oxidant, and increased pH. This project provided an overview of persulfate activation methods with application examples of the degradation of different compounds at wide concentration ranges in aqueous matrices that included ultrapure water, groundwater, and wastewater. The most viable activators, such as ferrous iron, chelated ferrous iron, and UV light, were chosen for studies in this research with the aim to implement these processes in situ in future. https://digi.lib.ttu.ee/i/file.php?DLID=9958&t=1
