Selective degradation of antibiotic in a novel CuS/peroxydisulfate system via heterogeneous Cu(III) formation: Performance, mechanism and toxicity evaluation.

Efficient degradation of antibiotic by peroxydisulfate (PDS)-based advanced oxidation processes in complex water environment is challenging due to the interference of impurities and the low activation efficiency of PDS caused by its symmetric structure. Herein, a novel CuS/PDS system was developed, which can selectively remove tetracycline hydrochloride (TC) without interference of inorganic ions (e.g.
