| Abstract: | A method of the determination of SO32- and SO42- in 5% ethylenediamine aqueous solution by ion chromatogra-phy was set up. The mixture solution of 3 mmol/L sodium carbonate - 10% methanol was used as the eluent. The separation column was a IonPac ASll. The method was convenient and reliable. The recovery of SO32- and SO42- was 97.6% - 101. 6% and 99.2% -101.0% , the RSD was 1.31% and 1.42% , respectively. |
