Abstract Sulfate radicals have been increasingly used for the pathogen inactivation due to their strong redox ability and high selectivity electron-rich species in last decade. The application of sulfate water disinfection has become a very promising technology. However, there is currently lack reviews inactivated pathogenic microorganisms. At same time, less attention paid by-products produced...

This work presents the valorization of Millettia laurentii carpentry sawdust waste into sustainable natural dye for ecological dyeing and functional finishing wool textiles. A simple aqueous extraction method was used to isolate dye, then extracted bio-dye subjected different qualitative quantitative analyses. Wool yarns were dyed in conjunction with metal salts (aluminum sulfate, ferrous coppe...

BACKGROUND Sulfur dioxide, formed during the combustion of fossil fuels, is a major air pollutant near large cities. Its two ionized forms in aqueous solution, sulfite and (bi)sulfite, are widely used as preservatives and antioxidants to prevent food and beverage spoilage. (Bi)sulfite can be oxidized by peroxidases to form the very reactive sulfur trioxide anion radical (*SO(3)-). This free rad...

1. The concentration-dependent scavenging abilities of zinc DL-methionine, zinc sulfate, zinc gluconate, zinc picolinate and selected free radical scavengers, including superoxide dismutase (SOD), catalase, mannitol, allopurinol and DL-methionine, were examined against biochemically generated superoxide anion, hydroxyl radical and hypochlorite radical plus hypochlorous acid, by chemiluminescenc...

Advanced oxidation processes (AOPs) based on oxidants have attracted attention for the degradation of organic pollutants. The combination chalcopyrite with such as persulfate, peroxide, percarbonate, and others shows promise a system due to its ability activate through various pathways, leading formation numerous radical non-radical species. In this review, generation sulfate (SR) hydroxyl (HR)...

This study explored the potential use of a sulfate radical (SO(·-) 4)-based photochemical oxidation process to treat the commercial nonionic surfactant octylphenol polyethoxylate (OPPE) Triton™ X-45. For this purpose, the effect of initial S2O(2-) 8 (0-5.0 mM) and OPPE (10-100 mg/L) concentrations on OPPE and its organic carbon content (TOC) removal were investigated at an initial reaction pH o...
