A Novel Catalytic Process for Degradation of Bisphenol A in Aqueous Solutions Using Fe Supported on Alginate/Carboxymethylcellulose

Research progress of metal–organic framework-based material activation of persulfate to degrade organic pollutants in water

“…Thus, there is an urgent need for economical and efficient technologies to control and reduce persistent organic pollutants. 1 At present, advanced oxidation techniques represented by Fenton oxidation, ozone oxidation, electrochemical oxidation, and photocatalytic oxidation are the main methods for organic wastewater treatment, 2–4 and all of the above mentioned methods achieve the effective degradation of organic matter in water by releasing strong oxidants into the system, such as hydroxyl radical (·OH), superoxide radical (·O 2 − ), and singlet oxygen ( 1 O 2 ), but the efficiency of oxidation treatment is relatively low. In recent years, advanced oxidation technology based on the release of persulfate radicals (·SO 4 − ) from peroxynitrite (PS) has become an efficient technology for the treatment of organic pollutants in water, and the redox potential of ·SO 4 − ( E 0 = 2.5–3.1 V) is slightly higher than that of ·OH ( E 0 = 1.8–2.7 V) and is more adaptable to the acidity and alkalinity of wastewater.…”
