摘要
本文介绍了用原子吸收光谱仪（ＡＡ）测定雪冰样品中主要阳离子浓度的技术。对比用火焰光度计和在美国用离子色谱仪测定的资料得出，这种方法对于测定中国西部冰川雪冰样品中的Ｎａ￣（＋），Ｃａ￣（２＋），Ｍｇ￣（２＋）浓度十分适合。提出使用正确的取样及样品运输方法以避免对雪冰样品的污染。
A determination of major cations in snow and ice cores by employing atomiceabsorption spectrophotometer（AA）is presented．Comparisons between the results and thedata measured using flame optical instrument and ion chromatography（ZC in United States）strongly the instrnment have done a good job to determine the concentrations of indicateNa^(＋)，Ca^(2＋)，Mg^(2＋)in the snow and ice cores collected in the mountains ofwestern China．Propersampling and sample transportation techniques are suggested to avoid contamination of thesnow and ice samples．
