Abstract: A new method was described for the determination of copper, iron and zinc in maize flour by micro-suspension sample introduction derivative flame atomic absorption spectrometry. The optimum conditions concerning trace elements the relative sensitivity the accuracy and the detection limits were 0.019μg/ml, 0.058μg/ml and 0.013μg/ml, respectively. This method was sensitive, accurate, precise and rapid.
