| 英文摘要 | A green, simple and convenient method for determination of cadmium and lead in PM2.5 by slurry sampling graphite furnace atomic absorption spectrometry was established. PM2.5 samples were collected from Changning district in Shanghai using quartz microfiber filters membranes and grinded into mu m-size fine particles by grinding mill for 4 min. The 0.7% Triton X-100 was used as dispersing agent and the pH value was adjusted to 2 by 1% HNO3. The detection limit of cadmium and lead was 0. 36 and 0. 06 mu g/L, respectively, and the linear correlation coefficient of the calibration curves of cadmium in the range of 0. 2-3 mu g/L and lead in the range of 0.1-75 mu g/L was better than 0.998, with a relative standard deviation being not more than 5.0%. The accuracy of the proposed method was verified by comparing the determination result with that by graphite furnace atomic absorption spectrometry and inductively coupled plasma mass spectrometry using solution of acid digestion. The pollution characteristics of cadmium and lead in PM2.5 were analyzed and the result showed that the trend of the mass concentration of PM2.5 with time was consistent with the trends of cadmium and lead. |
