  • Description: Advanced oxidation processes (AOPs) based on peroxymonosulfate (PMS) activation has attracted extensive attention in wastewater remediation. Although traditional transition metal or metal oxide-based catalysts exhibit high efficiency in PMS activation, they inevitably suffer from metal leaching. Herein, the S pirulina residue graphene oxide (SRGO) was synthesized as a bio-GO to effectively activate PMS to degrade sulfathiazole (STZ). After analysis, the performance of SRGO was highly related to salinity, and the high-salinity group named as SRGO-HS/PMS represented a remarkable STZ degradation. Notably, electron spin resonance (ESR), electrochemical and quenching experiments clearly indicated that the degradation of STZ in SRGO-HS/PMS was mainly occurred by the non-radical reactions based on singlet oxygen (1O2) and electron transfer, suggesting its high sustainability. Together, this work not only provides an appropriate platform for waste biomass conversion, but also offers a new idea for expanding the application of integrating bio-GO and AOPs to remove antibiotics from water
