【摘要】 本文介绍了利用火焰原子吸收分光光度法对宁夏野生白刺果汁上浮物中的铜、锌、铁、锰、钾、钠、钙和镁含量进行的研究工作。白刺果汁上浮物经湿消解法处理后，用原子吸收法测定。方法简单、快速，具有灵敏度和精密度高，选择性好，试剂消耗量小等优点。本法测定铜、锌、铁、钙、钾、钠、钙和镁的回收率均在９１．１～１０７．２％范围之间。变异系数均不超过５．３％。结果满意。更多还原

【Abstract】 Determinations of copper, zinc, iron, manganese, potassium, sodium, calciumand magnesium, as micro elements in the up-float of wild white stab fruit juice, are described by flame atomic absorption spectrophotometry. The method is easy and rapid. The sensitivity and precision are high. Recoveries of these eight elements are between91. 1～107. 2%, and variation coefficients are below 5. 3%.更多还原
