| 摘 要： | 通过电感耦合等离子发光分析装置（ICP-AES）确立了大气颗粒物中硫元素的全含量定量方法,认为颗粒物中硫元素全含量等于水溶性硫和残渣酸分解硫之和。文章利用该方法,分析了东莞市不同粒径大气颗粒物中硫元素的特征,其特征是随着颗粒物粒径的变小硫元素的浓度而增加,水溶性成分所占比例也随之上升。进一步分析大气颗粒物中的离子浓度,粒径小于2μm大气颗粒物中99%的硫元素都属于水溶性成分,并且其主要化学形态为硫酸铵。 |

| Abstract: | An anlytical method using ICP-AES was developed for the quantification of total sulfur in atmospheric particles,including water-solvable and acid-solved sulfides.In the study,it was investigated that the Chacterizations of total sulfur distributed with different diameters in aerosol particles.The results showed that the contents of total sulfur increased with the increasing diameter of particle,and the solvable sulfur increased as well.It was found that 99 % of total sulfur could be identified as water-solvable sulfur and the chemical sulfur specie was（NH4）2SO4 in the atmospheric particles of diamter less than 2 μm with advanced research. |
| Keywords: | atmospheric particles particle diameter total Sulfur quantification analysis |
