Oxidation of Bisphenol A and Related Compounds

open access: yesBioscience, Biotechnology and Biochemistry, 2001
Bisphenol A was oxidized to monoquinone and bisquinone derivatives by Fremy's salt, a radical oxidant, though salcomine and alkali did not catalyze the oxidation by molecular oxygen. Bisphenol A, bisphenol B, and 3,4'-(1-methylethylidene)bisphenol were converted to their monoquinone derivatives in the presence of tyrosinase at 25 degrees C at pH 6.5 ...

Chlorination of bisphenol A in aqueous media: formation of chlorinated bisphenol A congeners and degradation to chlorinated phenolic compounds

Chemosphere, 2002
The chlorination of bisphenol A (BPA) in aqueous media was investigated in order to describe the degradation profile of this compound and the formation of chlorinated products. Aqueous solutions of BPA (approx. 1 mg/l) were chlorinated by sodium hypochlorite solution at room temperature and under weakly alkaline conditions.

Rejection of endocrine disrupting compounds (bisphenol A, bisphenol F and triethyleneglycol dimethacrylate) by membrane technologies

Desalination, 2007
Application of membrane technologies as treatment for wastewater has grown in recent years. Accordingly, this study aimed to determine the retention capacity of these technologies for high concentrations of non-charged organic molecules such as endocrine disrupters (bisphenol A, bisphenol F and triethyleneglycol dimethacrylate or TEGDMA), which are ...

Environmental and occupational exposure to bisphenol compounds in Finland

Toxicology Letters
The aim of the study was to assess non-occupational and occupational exposure to bisphenol compounds in Finland. The participants were 151 non-occupationally exposed volunteers and 15 potentially exposed employees of a sewage-pipe relining company and a floor-coating company. The following chemicals were measured in the urine samples: bisphenol A (BPA),
