| Abstract: | The method for the determination of corrosion medium Cl- and SO42- in scale of boiler tubes in power station by ion chromatography was introduced. The method of on-line device supplying eluent with that of directly confecting duent was compared. Application characteristics of the device were obtained. The RSD of Cl- and SO42- was 2. 7% and 2. 3% , and the recovery was 89.0% -97.8% and 91.0% -98.9% ,respectively. |
