Removal of phenylamide pesticides from drinking waters—I. Effect of chemical coagulation and oxidants

Abstract Chemical coagulation with aluminium or ferric sulphates is not an effective mean for the removal of phenylamide pesticides from drinking water. The effects of chlorine, u.v.-catalyzed chlorination and chlorine dioxide on phenylamides were investigated. Several aniline derivatives and intermediate products having the amide linkage intact were detected in the treated solutions. The presence of such degradation products may exert the same undesirable effects on water quality as the parent compounds. Chlorine dioxide tends to be the oxidant of choice for the removal of phenylamides from polluted waters.
