A routine method for the determination of chloride, nitrate and sulfat
e anions in rainwater by capillary electrophoresis was developed. The
system uses an end-column non-suppressed conductivity detector. Linear
calibration plots were generated from 0.050 to 20 mg/l, which is the
range generally found in wet depositions. Accuracy and precision were
evaluated by analyzing certified standards of simulated rainwater and
environmental samples, or by comparing CE results with those obtained
by IC, the reference technique for anion analysis in wet deposition. T
he reproducibility of the method was satisfactory except at the lower
and upper limits of the analytical range. Sensitivity lay in the range
of few mu g/l.
