The simultaneous removal of bisphenol A, manganese and ammonium from groundwater by MeOx: the role of chemical catalytic oxidation for bisphenol A

Abstract Iron and manganese oxide filter film (MeOx) was used to research the simultaneous removal of bisphenol A (BPA), (Mn2+) ammonium (NH4+) in a pilot-scale system. We found that 0.52 mg/L BPA could be removed while consuming 5.44 dissolved oxygen (DO). Since oxidation process NH4+ both consume DO water, presence can hinder BPA. The Mn2+ water had synergistic effect on removal. characterized by SEM, XRD XPS. Some substances were generated block pores film, small amount crack fall off. elemental composition C O increased about 9.00%, Mn decreased from 63.48% 44.55%, reduced substance might affect activity film. main chemical forms MeOx Mn6O12·3H2O, MnFe2O4 Mn3O4. decrease efficiency mainly due C-containing intermediate [−CH2C − H(OH)]n covering surface blocking pore size
