提出了一种新的原子吸收光谱法,即悬浮液进样火焰原子吸收光谱法.并用于面粉中铁锌的测定.将面粉配制成悬浮液,直接喷入空气-乙炔火焰.用标准加入法测定.测定结果与灰化法一致.方法简便快速.
A new atomic absorption spectrometry (FAAS) method was proposed for the determination of iron and zinc in flour by suspension sampling, and the flour was prepared into a suspension and directly injected into the air-acetylene flame. The determination result is consistent with ashing method. The method is simple and fast.
