Abstract: The influence of three various Fenton oxidation techniques on the degradation of hydrolyzed polyacrylamide (HPAM) was studied at ambient temperature, and UV/ Fenton/C4H4O62- was found to be the best among the three techniques. The effect of various ions in the wastewater on the degradation of HPAM was investigated using Fenton/C4H4O62- reagent having stoichiometric ratios of [H2O2]: [Fe2+]: [C4H4O62-] = 10:1:1. The results showed that some negative effects were observed on the degradation of HPAM by the tested ions, under the testing conditions, the influence of these ions was in the order of Cl->Na+>SO42-.
