| 摘 要： | 利用离子色谱法测量了广州白云山春季降水及广西苗儿山云雾水中的甲酸和乙酸,并同时测定了降水中阴离子(F~-,Cl~-,SO_4~(2-),NO_3~-)和阳离子(Na~+,NH_4~+,K~+,Ca~(2+),Mg~(2+)。用多元逐步回归、多对多双重筛选回归及R聚类分析的多元统计的数学方法分析了降水中有机弱酸间及与阴阳离子间的关系。讨论了有机酸的来源及其对酸雨中酸度的贡献。

| Abstract: | Formic acid and acetic acid in acid rain cellected on the top of Bai-yun Mountain, Guangzhou and in fog from top of Miaoer Mountain(2140 m) ,Guangxi Province in spring of 1988 were determined by IC. The anion (F-, C1-, SO42- and NO3-) and cation (Na+, NH4+, K+, Ca2+, Mg2+) in the samples were measured as well. The relation between contents of organic acid and inorganic ion contents was analyzed using multivariate regression model and the contribution of organic acids to free acidity and the sources of the organic acids were also discussed. |
