摘要
本文应用FAAS法直接测定大气降水中阳离子K+、Na+、Ca2+、Mg2+。通过对火焰状态的选择,以减少和抑制电离的干扰。方法简便、快速、准确。加标回收率在94.0%-105.2%之间,RSD<5.07%。
FAAS is applied to determine K+, Na+, Ca2+ and Mg2+in rainfall and the ionization interference is repressed by optimizing the flame. The results show the method is characterized by convenience and accuracy. The recovery rate is 94. 0%- 105. 2% and the relative standard deviation is less than 5. 1%.
