1 Scope This standard specifies flame atomic absorption spectrometry, inductively coupled plasma atomic emission spectrometry and inductively coupled plasma mass spectrometry for the determination of iron content in foods. This standard is applicable to the determination of iron content in foods. Method I Flame Atomic Absorption Spectrometry 2 Principle After the digestion of specimen, and the atomic absorption flame atomization, the absorbance value is determined at 248.3nm. Within the range of certain concentration, the absorbance value of iron is in direct proportion to the iron content and quantitation is realized by comparing with standard series. 3 Reagents and Materials Unless otherwise specified, guaranteed reagents and Grade II water (defined in GB/T 6682) are adopted for the purposes of this method. 3.1 Reagents 3.1.1 Nitric acid (HNO3). 3.1.2 Perchloric acid (HClO4). 3.1.3 Sulfuric acid (H2SO4). 3.2 Reagents preparation 3.2.1 Nitric acid solution (5+95): measure 500mL of nitric acid, pour it into 950mL of water and mix well. 3.2.2 Nitric acid solution (1+1): measure 250mL of nitric acid, pour it into 250mL of water and mix well.
