邻二氮菲分光光度法测定几种日常食物中的铁含量

o-Phenanthroline Spectrophotometry method to Determine Microelement Iron in Several Kinds of Common Food

利用有机物破坏法消化样品,再采用邻二氮菲分光光度法测定常见食品中铁的含量。该方法操作简便、准确性高、重复性好。为人们选择食物补充每日所需铁量提供一定的理论依据。

The samples have been decomposed by using organic degradation. Microelement Iron in Several Kinds of Common Food had been determined by o-phenanthroline spectrophotometry. The method is simple operation, high accuracy and good reproducibility. The result provides the theoretical basis for people choosing common food to replenish iron.
