摘　　要：用0.1%硝酸溶液配制混合标准溶液,不加抗干扰试剂,火焰原子吸收光谱法直接测定酸雨中K、Na、Ca、Mg,方法精密度、准确度满足酸雨监测的分析要求。The standard solution was prepared by 0. 1 percent nitric acid, no any anti-interference reagents needed. The potassium, sodium, calcium and magnesium in acid rain were determined by FAAS. The accuracy and precision of the improved method meted the requirements of acid rain monitoring.
