The present paper established a new method for analyzing cations in 75% IPA which was used to extract anions and cations from the surface of PCB by ion chromatography method.The chromatographic equipment consisted of an IonPac CS12A cation exchange column and 18 mmol/L of MSA isocratic eluent coupled with a suppressed conductivity digital detection meter that could achieve good reproducibility,selectivity,sensitivity and veracious results.Also this method could give good linear range and spiked recoveries as well.
