Comparison of oxidation efficiency of EDTA by different processes (b) and the changes in the temperature of the solution (a): (1) Fenton, (2) UV/Fenton, (3) Fenton + K2C2O4, (4) UV/Fenton + tert-butanol (5) Fenton + K2C2O4 + tert-butanol.
Experimental conditions: EDTA: 50 mM, H2O2: 1.5 M, Fe2+: 15 mM, K2C2O4: 11 mM, tert-butanol: 10 mM.
