文摘

Combined use of peroxymonosulfate and KMnO4 (CUPP) showed powerful oxidizing ability. Colloidal/amorphous MnO2 from KMnO4 reduction can activate peroxymonosulfate. Amorphous MnO2-activated PMS showed adsorption-dependent oxidizing capability. Chloride, bicarbonate and phosphate showed different effects on the oxidizing ability. CUPP is simple but very applicable for in-situ remediation of contaminated groundwater.
