A capillary electrophoresis (CE) method was developed to separate and
determine residues of two sulfonylurea herbicides (primisulfuron and t
riasulfuron) in water and soil samples. Fortified water samples were e
xtracted by solvent partitioning with methylene chloride and analysis
by CE. Fortified soil samples were extracted by shaking in methanol-ph
osphate buffer (1:1) followed by partitioning of the residues into met
hylene chloride and analysis by CE. The method was simple, rapid and y
ielded excellent recoveries. Average recoveries were greater than 90%
for both herbicides fortified at 10 mu g/l in lakewater samples and at
50 mu g/kg in soil samples. Our results demonstrate that capillary el
ectrophoresis provides a powerful analytical tool for determination of
the residues of primisulfuron and triasulfuron in water and soil samp
les.
