Stability and reusability are important characteristics of advanced catalysts for wastewater treatment. In this work, for the first time, sulfate radicals (SO4∙-) with a high oxidative potential (Eo = 2.5-3.1 V) were successfully activated from persulfate by a Fe78Si9B13 metallic glass. This alloy exhibited a superior surface stability and reusability while activating persulfate as indicated by...

BACKGROUND Occupational and environmental factors may be a cause of nonasthmatic eosinophilic bronchitis (NAEB). The diagnosis of occupational NAEB requires evidence of sputum eosinophilia. Nevertheless, a minority of patients are not able to produce suitable sputum specimens. METHODS This case report describes a 25-year-old woman, working as a hairdresser since the age of 20 years and handli...

In this study, nanoscale zero-valent copper (nZVC) as catalyst activated persulfate (PS) was used for the degradation of p-chlorophenol (p-CP) under ultrasonic (US) irradiation in aqueous solution. The effect of different operational parameters such as solution pH (3.5-10.5), PS concentration (1-7.5 mm/L), nZVC dosage (5-35 mg/L) and initial p-CP concentration (10-100 mg/L) were evaluated at di...

Introduction. Azithromycin is among the broad-spectrum antibiotics that is widely available in various environmental systems and could have destructive effects on the ecosystem and human health due to its bacterial resistance. In this study, removal of azithromycin from wastewater using an advanced oxidation process of ultraviolet light with and without persulfate was investigated and effective...

The Mo-based polyoxometalates containing mono- and dicobalt(III) catalyst cores, [CoMo(6)O(24)H(6)](3-) and [Co(2)Mo(10)O(38)H(4)](6-), were found to serve as O(2)-evolving catalysts in a system consisting of tris(2,2'-bipyridine)ruthenium(II) (Ru(bpy)(3)(2+)) and sodium persulfate (S(2)O) in an aqueous borate buffer solution at pH 8.0. Kinetics of O(2) evolution reveals that the higher cobalt ...

In recent years, typical organic pollutants were frequently found in aquatic environments. Among them, synthetic dyes widely used many industries, which resulting a large amount of wastewater contained dyes. Because the characteristic complex components, poor biodegradability and high toxicity, this kind brought lots harm to ecological environment organism. study, three different types manganes...
