摘　　要：电感耦合等离子体发射光谱法和火焰原子吸收分光光度法测定天然水体中钾、钠、钙、镁,比较相关系数、检出限、精密度、准确度和实际样品的测定,结果表明:两种方法均可用于天然水体中钾、钠、钙、镁的测定,且电感耦合等离子体发射光谱法更优。Inductively coupled plasma emission spectroscopy and flame atomic absorption spectrophotometry were used to determine potassium,sodium,calcium,and magnesium in natural water bodies.The correlation coefficient,detection limit,precision,accuracy,and sample determination were compared.The results showed that both methods could be used for the determination of potassium,sodium,calcium,and magnesium in natural water bodies,and the emission spectroscopy method was superior.
