| Abstract: | The method for determining NO2 , SO2 in air and emission gas by ion chromatography was studied. 20 mmol/L KOH was used for solution at the flow rate of 1 mL/min. The fitting cures for detection were analysed. The standard solution for controling quality was determined by the method, and the deviations were within the error range. The limit of detection was less than 0.01 mg/m3, which met the demand of GB 3096. Compared with the typical monitoring method, handy operation, lower consumption and high sensitivity were shown on the researched method. |
