Abstract
A liquid‐liquid extraction method using dichloromethane: ethyl acetate (50:50) + 0.2M ammonium formate has been developed for the trace analysis of chlorotriazine herbicides and its degradation products in the range of 100—0.1 ppb using spiked water samples. The method has been compared with the most widely used with dichloromethane. Analysis has been carried out by liquid chromatography with diode array detection. The structured and distinctive UV spectral information allows to differentiate between the chlorotriazines and its metabolites.Keywords
