摘要：
Batch experiments were carried out to investigate the efficiency of ozone treatment on the removal of non-ionic surfactants from aqueous solutions. A series of nonyl phenol ethoxylates, with n equals 4 to 30 ethylene oxide groups, dinonyl phenol ethoxylate and polyethylene glycol were studied. The oxidation mechanism by ozone of non-ionic surfactant molecules is explained as mainly polyethoxylate chains cleavage, and to a smaller extent oxidation of the aromatic ring. Ozone treatment can enhance biodegradation of these surfactants.
