Abstract:
      In this work, a Dionex IonPac AS22-fast(4 mm×150 mm)anion exchange column was chosen for the fast determination of common anions in simple matrix samples. By optimizing the chromatographic conditions including flow rate and eluent concentration, etc., seven common anions, which are fluoride, chloride, nitrite, nitrate, bromide, phosphate and sulfate,were separated completely within 3.5 min. By application of the method, the fast determination of common anions in simple matrix sample can be achieved.
