摘要
以离子色谱法测定了厦门市海洋性降水中的甲、乙酸及某些阴、阳离子。用多元逐步回归和多对多双重筛选回归等数学方法,分析了降水中弱有机酸及其与阴阳离子的关系;讨论了其来源及对厦门酸雨的贡献。
Formic acid and acetic acid in precipitation of Xiamen Island were determined by IC, and the anion (F^-,Cl^-,NO_3,SO_4^(2-)) and cation (Na^+, NH_4^+, K^-,Ca^(2-), Mg^(2-) in air samples were measured as well. The relationships between contents of organic acids and inorganic ions were analyzed by using multivariate regression model, and the maximum contribution of organic acids to free acidity and sources of them were also discussed.
