摘要：

The degradation of polyacrylamide (PAM) in simulate wastewater was studied in UV/Fenton/C4H4O62- system. The factors such as molecular ratio of H2O2/Fe2+/C4H4O62-, pH, and the dosage of Fenton reagent that could affect the PAM degradation in the UV/Fenton/C4H4O62- system were investigated. The experimental results showed that adding C4H4O62- to UV/Fenton system could form photosensitive ferrous complexes, which led to higher degradation efficiency of PAM. The degradation rate of PAM could be up to 95.2% under the following conditions: the concentration of H2O2, Fe2+, and C4H4O62- were 22.5, 2.25, and 2.25 mmol/L, respectively (i.e., molecular ratio of H2O2/Fe2+/C4H4O62- was 10:1:1), the pH value was 3.0.
