The study of photodegradation of dimethenamid-P herbicide was performed in deionised and ground water using TiO2 as a catalyst under UV light. The effect of electron acceptor (H2O2), scavenger of (OH)-O-center dot radicals (C2H5OH) and scavenger of holes (NaCl and Na2SO4) as well as solution pH was analyzed. The photodegradation of dimethenamid-P was followed by HPLC. The formation of transformation products was followed using high performance liquid chromatography-electrospray mass spectrometry. Ion chromatography and total organic carbon measurements were used for the determination of the mineralization level. HPLC analysis showed the almost complete removal of herbicide after 90 min in deionised and ground water, while total organic carbon analysis showed that dimethenamid-P was mineralized 64 and 50% in deionised and ground water, respectively. The ion chromatography results showed that the mineralization process leads to the formation of chloride, sulphate and nitrate anions durin...g the process. Transformation products were identified and the degradation mechanism was proposed.
