[The determination of the herbicide glyphosate and its chief metabolite aminomethylphosphonic acid (AMPA) in drinking water with the aid of HPLC].
A method for the determination of glyphosate and its major metabolite aminomethylphosphonic acid (AMPA) is described. With a detection limit of 0.02 microgram/l, the method suitably fulfills the requirements of the Swiss legislation (tolerance value of 0.1 micrograms/l water). The compounds are derivatized directly in the original water sample with 9-fluorenylmethyl chloroformate (FMOCC1) in order to obtain extractable and fluorescent derivatives. These are extracted with organic solvents and determined by HPLC using a fluorescence detector. Neither of the compounds could be detected in 151 tap water samples from the Canton of Berne.
