Sodium isopropyl xanthate degradation by advanced oxidation processes

► Advanced oxidation processes emerges as a new technology for wastewater treatment. ► Photoelectrooxidation and UV-photolysis show similar kinetics, larger than electrolysis. ► The kinetic mechanism developed fits the SIPX degradation kinetics. ► The developed kinetic mechanism helps in interpreting the results. ► Possible to differentiate the action of direct and indirect SIPX degradation.
