A decomposition of phenolic endocrine disrupting chemicals (2,4-dichlorophenol, nonylphenol and bisphenol A) in aqueous solutions by potassium permanganate was tested. A solid phase micro extraction-gas chromatographic (SPME-GC) method was used for the analysis. Each compound (1 mg/L) in the mixed solution was completely decomposed by potassium permanganate (64 mg/L) within 60 min. The reaction efficiency was in the order of nonylphenol>bisphenol A>2,4-dichlorophenol>phenol.
