火焰原子吸收光谱法测定各种条件下不同炊具中铁等元素的含量

Determination of Content of Iron in Different Cooking Utensils in Different Conditions by Flame Atomic Absorption Spectrophotometry

应用火焰原子吸收光谱法测定了各种条件下不同炊具中铁元素和其它元素的含量。得出在非酸性环境下使用任何一类炊具都不能增加食物中铁元素的含量,使用铁炊具、不锈钢炊具及铝炊具并无多少区别。在微酸性条件下,使用铁炊具可以使食物中的铁元素的含量比中性条件下增加74倍,比在微碱性条件下增加146倍。

The content of iron and other elements in different cooking utensils in different condition has been determined with flame atomic absorption spectrophotometry. Through experiments it has been found in non-acidic condition iron element in food cannot be increased by using any kinds of cooking utensils and there,s not so much difference between iron cooking utensils and stainless steel and aluminium utensils . In alkalescent condition the iron element in food will be reduced . But in acidic condition the amount of iron element in food by using iron cooking utensils can be 74 times greater than in nearly condition and 146 times greater than in acidic condition.
