  The coexistence of tetracycline (TC) and arsenite (As(III)) in livestock
wastewater threatens public health, and the heterogeneous Fenton-like system is
a practical approach for the simultaneous removal of TC and As(III). In this
work, fine CoFe$_2$O$_4$ nanoparticles are facilely anchored on heretically
porous carbon (CoFe$_2$O$_4$@PC) via a microwave-assisted calcination method
and used for eliminating TC and As(III) via peroxymonosulfate (PMS) activation.
