In order to detect chlorate in ammonium nitrate explosive, the soil sample after explosion was extracted by water oscillation,then taking supernatant after centrifugation, filtered by IC-RP column and 0.22 um microporous filtration membrane.Using CIC-D120 ion chromatograph, SH-AC-12B anion column, 4.0 mM Na2CO3 eluent and bipolar pulse conductance method, under the recommended chromatographic conditions, the chromatogram is as follows.
