The degradation of highly stable oilfield pollutants by supported zero-valent transition metals in a dual-oxidation system
Published 2024-12-01“…Cu0@LDHs was used to activate the hydrogen peroxide-sodium persulfate(H2O2-Na2S2O8) dual-oxidation system for the degradation of oilfield hydroxypropyl guar gum (HPG). Based on the optimization of reaction conditions, it was found that within the pH range of 3 to 11, the H2O2-Na2S2O8 dual-oxidation system still maintained a high degradation effect on HPG, with degradation rates higher than 76.30% at 25 min, and COD removal rate of 93.91% after 120 min. …”
