摘要
本文用冷凝法采集雾水样品,用离子色谱法测定雾水样品中阴离子(氟离子、氯离子、亚硝酸根离子、硝酸根离子、硫酸根离子)的浓度,研究表明雾水中阴离子浓度与雾的浓密有关,雾水中硫酸根离子含量最高;雾水中阴离子浓度随大雾的消失而降低;雾水中阴离子浓度大于雨水。所得结果对在大雾天气情况下保护人体健康有一定参考意义。
In this paper fog water was collected by means of condensation.The anions of F-,Cl-,NO-2,NO-3 and SO2-4 in the fog water were determined by ion chromatography.The results showed that the anion concentrations in fog water were related to the density of the fog;SO2-4 had the highest content;anion concentrations gradually decreased with the dissipation of the fog;and the anion concentrations were higher than that in rain water.The results may be helpful to protect human health in the heavy fog.
