The kinetics, environmental influencing factors, products and reaction mechanism of aqueous phototransformation of bisphenol S (BPS), as an alternative to bisphenol A, which is of environmental concern, were investigated. p-Hydroxybenzenesulfonic acid, as the major transformation product was confirmed by gas chromatography - mass spectrometry, electrospray ionization, ¹H nuclear magnetic resona...

BACKGROUND Bisphenol AF has been acknowledged to be useful for the production of CF3-containing polymers with improved chemical, thermal, and mechanical properties. Because of the lack of adequate toxicity data, bisphenol AF has been nominated for comprehensive toxicological characterization. OBJECTIVES We aimed to determine the relative preference of bisphenol AF for the human nuclear estrog...

background: bisphenol-a is categorized as a toxic and refractory organic matter. ultrasonic process considered as an effective method for degradation of refractory organic matters in the environment which is achieved by the production of fine bubbles through cavitation process. this study is conducted for assessment of the toxicity of effluents containing bisphenol-a which was treated by ultras...

bisphenol a, 2,2-bis(4,4-dihyroxyphenyl propane) is the raw material for the production of important synthetic polymers such as epoxyresins, polycarbonates and polysulphones. during the last twenty years the anual production of bisphenol-a has been continuously increasing. a,b,c cqrves shows the consumption pattern of bisphenol-a (19601972) • epoxy resins are used for the production of adhessiv...

Bisphenol A, bisphenol S, and fluconazole are environmental contaminants widely found in surface waters because of their extensive usage low biodegradability. Therefore, other methods often considered for the removal these compounds. The present study aims at photodegradation with use UV light three different catalysts, ZnO, TiO2, Ag-TiO2. results obtained show that photocatalytic compounds is ...
