| Abstract: | A new FAAS method for the determination of zinc and iron in maize flour using suspension sample introduction is described. The maize flour was suspended in agar sol, and injected into air-acetylene flame by using standard addition method to determine zinc and iron. The results are consistent with those obtained by ashing method. This method is convenient and rapid. |
