摘要
用 HPICE 法测定了降水,雾水、雪水中的有机酸,最佳分析条件为淋洗液中 H_3BO_3浓度大于0.2M,HNO_3浓度在0.1mM～0.2mM 范围。分析结果用 I％D 计算法计算离子平衡。有机酸对离子平衡情况有所改善。考察了有机酸的稳定性。
Organic acids in rain fog and snow have been measured by the way of HPICE andits best analytical condition has been selected.The experimental concentrition in elution isover 0.2M for H_3BO_3,0.1mM to 0.2mM for HNO_3.The result was used to calculate the ionbalance in solution by the way of I%D.Organic acids contribute to ion balance.The stabilityOf organic acid is studied as well.
