| Abstract: | Using triethanolamine as absorption solution to capture various air pollutants simultaneously in one sample, it’s absorption efficiency is high. The determination is carride out by an ion chromatograph on 3μs grade. With 5ml absorption solution to collect 30 litres of air sample, the detection limit (mg/m3) for F, Cl, NO2 and SO2 is 0. 003, 0. 006, 0. 008 and 0. 011 respectively. The variation cofficients of the method are 2. 76% for NO2 and 5. 5% for SO2. The recoveries of NO2 and SO2 are 96%-104% and 93%-110% respectively. |
