Widespread usage of bisphenol A (BPA) and its potential replacement bisphenol S (BPS) has led to their presence in natural waterbodies. The experimental research into degradation of both aqueous pollutants by application of gas-phase pulsed corona discharge (PCD) was undertaken with variation of process control parameters, pulse repetition frequency, gas–liquid contact surface and addition of surfactant OH-radical scavenger sodium dodecyl sulphate (SDS). Although the contact surface variation had only a moderate impact on bisphenols degradation, its effect was stronger in total organic carbon removal. The addition of SDS showed a moderately negative impact on energy efficiency at all studied conditions. The obtained results showed energy efficiency surpassing the closest competitors, ozonation and other electric discharge processes. The detected major oxidation intermediates were mainly formed through hydroxylation and cracking of benzene rings, followed by further degradation into short chained aliphatic acids. The oxidation end-products were quantified as acetate, formate and oxalate.
