The removal of dimethyl phthalate (DMP), which is a pollutant of concern in water environments, was carried out by sodium persulfate (SPS,Na2S2O8) catalyzed by Ag+combined with microwave irradiation. Effects of persulfate concentration, reaction time, microwave(MW) power and catalytic ion Ag+ on the degradation efficiency of DMP by persulfate were examined in batch experiments. The results showed that optimum Na2S2O8 concentration was 0.083mmol/L, and Ag+ concentration was 0.042 mmol/L. Increasing the MW irradiation time , persulfate concentration or Ag+ concentration might significantly accelerate DMP degradation. Catalytic ion Ag+combined with microwave irradiation was an rapid method to activate persulfate, and thus to produce SO4−• which was a powerful oxidant and could degrade DMP effectively. About 80% of DMP and 70% of COD could be degraded in 140s under the conditions of 800W MW power.

Chitosans with high and low molecular weight were intercalated into organic rectorite to prepare nanocomposites via a microwave irradiation method for 75 min, which was much more efficient than the conventional 48 h heating method.
