Separation and Determination of Inorganic Sulfur Anions by Mobile Phase Ion Chromatography

Jia Zhongjiang~* Yu Zhongquan (Institute of Chemical Metallurgy Academia Sinica Beijing 100080)  
The effects of various factors on the capacity factors of SO_4~(2-), S_2O_3~(2-) and SnO_6~(2-) (n =2~5) were investigated and discussed systematically by mobile phase ion chromatography. The optimal chromatographic conditions for the separation and determination of these anions were obtained. The separation time is 16 minutes. The detection limits are at μg/ml~ng/ml levels. This is a comparatively fast, sensitive and accurate method for the chromatographic analysis of inorganic sulfur anions.
