摘要
本文通过 HNO3- HF- HCl O4 混合酸消解法对凡士林样品进行前处理 ,采用火焰原子吸收光谱法同时测定微量铅和镉 ,并与其他前处理方法进行比较。该法简便快速、准确实用 。
The sample was pretreated for digestion with the mixed acids of HNO 3-HF-HClO 4 ,and then the flame atomic absorption spectrometry was developed for the simultaneous determination of lead and cadmium in vaseline.Herein it was compared with other pretreatment methods.This method is convenient,rapid,practical and accurate with high precision and recovery.
