Transformation of bisphenol AF and bisphenol S by manganese dioxide and effect of iodide

In this work, transformation of bisphenol A (BPA) alternatives bisphenol AF (BPAF) and bisphenol S (BPS) by manganese dioxide (MnO2) and the effect of iodide (I−) during these processes were investigated in comparison with BPA for the first time. These three bisphenols showed appreciable reactivity towards MnO2 with the half-lives of their loss following the order of BPA BPS.•I− significantly enhanced the transformation of BPAF and BPS by MnO2 at pH ≤ 7.•Polymeric, hydroxylated, and bond-cleavage products were detected from BPAF/BPS treated by MnO2.•Iodinated aromatic products were generated from MnO2/BPAF(BPS)/I− systems.
