1 Scope
This standard specifies the graphite furnace atomic absorption spectrometry, atomic fluorescence spectrometry, inductively coupled plasma mass spectrometry, inductively coupled plasma atomic emission spectrometry and malachite green spectrophotometery for determination of migration of antimony after soaking the food contact materials and articles in food simulants.
This standard is applicable to the determination of migration of antimony in food contact materials and articles.
Method I Graphite Furnace Atomic Absorption Spectrometry
2 Principle
Soak the parts of the food contact materials and articles which are expected to contact with food in the food simulants, atomize the soak solution by the graphite furnace; within certain concentration range, the absorption value determined at 231.2 nm is in direct proportion to the antimony content and is compared with standard series for quantification.
3 Reagents and Materials
Unless otherwise specified, guaranteed reagents and Class-II water (defined in GB/T 6682) are adopted for the purpose of this method.
