Co–CuBi2O4 and Cu–CuBi2O4 were synthesized for SA degradation via PMS activation.
Effects of pH, L and D on SA degradation were investigated.
Effects of common water matrix species on SA degradation were assessed.
Empirical relationship between kapp, L and D was obtained.
A method to calculate [SO4−]Nss and [
OH]Nss is proposed.
