Degradation of organic pollutants using a ternary heterojunction catalyst (CoS 2 /CoCo 2 O 4 –MnFe 2 O 4 ) for activating peroxymonosulfate with magnetic separation, anti-ion interference, and low ion leaching

Activating persulfate to generate reactive oxygen species (ROS) for the effective degradation of toxic organic compounds is an important research topic in environmental management.
