水中钾、钠两种测定方法的比较研究
任妍冰
连云港市环境监测中心站
摘要:
对测定水中钾、钠的两种方法——离子色谱法和电感耦合等离子体原子发射光谱法在检出限、校准曲线、精密度、准确度等方面进行了全面比较,并进行了干扰实验研究,得出两者精密度小于5%,准确度符合要求,两者的测定结果无显著性差异。

Abstract:
This paper compared IC and ICP〖CD2〗AES in aspects of calibration curve, detection limit, precision and accuracy of determining sodium and potassium in water. The interference experiment was also conducted. The results showed the precision was less than 5% and accuracy conformed to the requirement. There were no significant differences between the measured results.
