摘要

•The specific pathways of BPA degradation by CO3•− were proposed.•BPA degradation by UV/SPC was less efficient than by UV/H2O2 in secondary effluent.•The increase of pH decreased [HO•]ss, thus decreasing the kobs in both systems.•The addition of HCO3− greatly decreased kobs by decreasing [HO•]ss and [CO3•−]ss.•NOM inhibited BPA degradation in the order of FA > mixed NOM > HA.
