Activation of Peroxymonosulfate Using Spent Li-Ion Batteries for the Efficient Degradation of Chloroquine Phosphate

Recycling and reusing spent lithium-ion batteries (LIBs) have gained a lot of attention in recent years, both ecologically commercially. The carbon nanotube-loaded CoFe2O4 (CoFe2O4@CNTs) composite was made using solvothermal technique utilizing wasted LIBs as the starting material nanotubes support, it used an efficient peroxymonosulfate (PMS, HSO5−) activator to degrade chloroquine phosphate (CQP). Scanning electron microscopy (SEM), transmission (TEM), energy dispersive spectrometer (EDS), X-ray diffraction (XRD), Brunauer–Emmett–Teller (BET), photoelectron spectroscopy (XPS) were utilized characterize physical chemical properties catalyst generated. impacts CoFe2O4@CNTs dosage, PMS concentration, reaction temperature, initial pH value, CQP co-existing ions undergone extensive experimental testing. In comparison bare CoFe2O4, demonstrated increased catalytic activity, which might be attributed their super transport capacity large surface area. ideal conditions, mineralization efficiency removal 10 mg/L approached 33 98.7%, respectively. By employing external magnets, may simply recycled reused several times. potential mechanism CoFe2O4@CNTs/PMS system also investigated. summary, this study indicates that generated from high activation for other pollutant degradation.
