摘要
应用实验和酸碱平衡计算的方法,研究青岛地区气溶胶的酸碱特性,测定气溶胶中硫酸的含量,推断气溶胶中的Ca2+,Mg2+的存在形式与SO2-4,NO-3的来源以及IP和TSP对降水酸性的贡献。发现IP气溶胶对降水总的影响是起中和作用,中和能力以碳酸盐计相当于它所含的钙、镁盐的(22±20)%。
By using experiments and acid base balance calculation, acid and base characteristics of ambient aerosols in Qingdao area was studied. The content of sulfuric acid in ambient aerosols was analyzed, the existing forms of Ca 2+ and Mg 2+ in ambient aerosols were deduced, the sources of SO 2- 4 and NO - 3 and the contribution of IP and TSP to rainwater acidification were estimated. It is found that the total effect of IP and TSP to rainwater is neutralization function, and their neutralization capability (carbonate) is about (22±20)% of the content of Ca and Mg in ambient aerosols.
