| Abstract: | The determination method of chloridion ion in quinolinic acid by ion chromatography suppressed conductivity detection was established.SH-AC-1 ion exchange column was used,the selected best chromatographic conditions as follows：1.8 mm sodium carbonate and 1.7 mm sodium bicarbonate mixture was as the eluent,column temperature was 45℃,the flow rate chosen was 1.5 mL·min-1.On these conditions,Cl anion was carried out with symmetric peak.The detection limit of Cl was 0.005 mg·L-1（S/N=3）.The recovery to determine Cl anion was between 96%～104%.This method is simple,accurate,reliable,and better practical applicability. |
