Effects of Alkalinity and Of Dissolved Organic Matter on the Degradation of Atrazine by O_3 and O_3/H_2O_2

摘要

The degradation of atrazine by the O_3/H_2O_2 oxidizing system in a continuous flow reactor has been examiend in this laboratory study. The preliminary reuslts showed the effects of the oxidant doses, of the H_2O_2/O_3 dosage ratio and of hte bicarbonate alkalinity on the rmoval yield of atrazine. For a given ozone dosage and for a given contact time, removal yields of atrazine were larger by O_3/H_2O_2 process than by ozonation alone.
