title: [Flame atomic absorption spectrophotometry for measurement of iron, manganese and zinc contents of wheat seeds].
abstract: The iron, manganese and zinc trace element contents of six different kinds of winter wheat seeds were studied by flame atomic absorption spectrophotometry. As a result, the rates of recovery of iron, manganese and zinc are 103.09%, 102.90% and 101.19%, respectively, and the relative standard deviations (RSDs) of Fe, Mn and Zn are smaller than 3.94%, 1.67% and 2.69%, respectively. Taking GBW08503 wheat flour as standard sample and carrying out comparative determination, the successful results were achieved. This method is very simple, rapid and accurate.
