A new method--suspension sampling technique was applied to flame atomic absorption spectrometry and was successfully used to determine Cu, Zn, Fe in Huaiyao. Then studied the choice of suspension agent and elimination of chemical interference. The huaiyao sample was suspended in agar sol, and injected into air-acetylene flame by using standard addition method to determine Cu, Zn, Fe. Determined results were consistent with those obtained by HNO3 + H2SO4 + HClO4 method. The t-test showed that no obvious difference was found between the two methods. Displacement of HNO3 + H2SO4 + HClO4 method by suspension sampling method for the sample pretreatment is possible. This method is convenient, rapid and accurate.
