Thiourea is a toxicant which will bring some adverse effects to the public health. In the study, thiourea was degraded via ozonation process. The results show that the ozonation is an effective method to remove thiourea from wastewaters. When the ozone flow rate was 600 cm³*min^-1, pH was 7.3, the temperature was 20 °C, 93.97% of thiourea (200 cm³ solution of 3 g dm^-3) could be degraded after 9 min of reaction. The reaction order of ozonation of thiourea n was 0.11, and the reaction rate constant k = 0.4898 g^0.89 (dm³)^-0.89*min ^-1.
