火焰原子吸收法测定葡萄糖饮料中的锌含量

Determination of Zinc in drink contained Glucose by flame atomic absorption spectrometry

本文用混酸 HNO3+HCl O3(3+1)消化葡萄糖饮料 ,利用火焰原子吸收法在λ=2 13.9nm处测定锌的含量 ,工作曲线 R=0 .9992 ,精密度为 0 .5 8% ,加标回收率为 10 5 .3% .结果令人满意 .

Put mixed acid(HNO 3+HClO 4)(3+1).into the drink containing glucose to digest it,then Zine in the drink can bi determined by FAAS,The relative standard(RSD) is 0.58% and recovery is about 105.3%.The result is satisfying.
