| Abstract: | Ti（ SO4 ）2 as an inorganic titanium salt, was used as the material to prepare nano -TiO2 by liquid phase precipitation method. The degradation rate of polyacrylamide （PAM） was investigated, and the effects of Ti^4＋ concentration, pH value, dosage of surfactant （DBS） and calcination temperature on the performances of TiO2 were studied. The results have shown that the degradation rate of PAM can reach 84.37% when Ti^4＋ concentration is 0.2 mol/L, pH value is 2, and mass ratio of DBS to Ti^4＋ is 1：10. |
