| Abstract: | The generating rule of hydroxyl radical of Fenton,UV/Fenton and UV/Fe(C2O4)33-/H2O2 system was investigated by using spectrophotometric method.The experimental results indicated: The generating sequences of hydroxyl radical were UV/Fe(C2O4)33-/H2O2>UV/Fenton>Fenton.The optimum K2C2O4concentration and pH ranges were 1 mmol/L and 2-5 in UV/Fe(C2O4)33-/H2O2 system.When H2O2 concentration reached 20 mmol/L,the generating quantity of hydroxyl radical was the biggest.The concentration of hydroxyl radical in UV/Fe... |
