| Abstract: | Few persons determine the trace elements in the licorice by X-ray fluorescence spectrometry (XRF), because there is no standard samples of the licorice. This paper describes the method to determine Sr,Zn,Cu and Fe in licorice using XRF. The samples are ashed and then determined with the powder process. The measured results are corrected by artificial standard samples. |
