Abstract
An analytical method was developed for the determination of glyphosate
and AMPA in water. This method involves derivatization in situ with NBD-Cl
reagent at 60 °C. The quantification is performed using liquid chromatography
with fluorescence detection after a separation on an amino column. The limit
of quantification was estimated at 1 g/L level for glyphosate and at 0.1
g/L
level for AMPA.
Key words: glyphosate -- AMPA -- analysis -- fluorescence -- NBD-Cl.
