Abstract

A new application of high resolution continuum source flame atomic absorption spectrometry has been developed for the determination of Fe and Zn in garbanzo. The selected fuel flows of Fe and Zn were 80 L/h and 90 L/h respectively, and the appropriate burner heights of Fe and Zn were 5 mm and 6 mm respectively by single factor experiments. Under the optimum working conditions, the proposed methods are fast, inexpensive and show good performances: the relative standard deviations were less than 2.6%, good correlation coefficients and the recoveries of Fe and Zn were 96.7%±2.5% and 94.3%±3.1%, respectively. The results showed that the contents of Fe and Zn in garbanzo were 68.6±1.5 mg/kg and 18.1±0.6 mg/kg, respectively. Therefore, the proposed method was accurate and stable with a high practical value. It provided scientific basis for determination of metal elements in food
