Verification of a method for microcoulometric determination of adsorbable organic halide pollutants in natural, drinking, waste, and treated waters.
A microcoulometric method is described for the determination of organic-halide pollutants at 2-2000 microg/L in natural, drinking, waste, and treated waters. The conditions for the adsorption of organic halides, using a microcolumn with activated charcoal-and for the desorption of inorganic halides-as well as for the pyrolysis process, were optimized for the successful determination of priority organic halide pollutants. An appropriate criterion was proposed to stop the desorption step. The mean recovery was 100.3%, and the mean relative standard deviation was 9.9%. The detection limit based on 3 times the standard deviation of the blank sample was 2 microg/L.
