摘要
本文介绍了在ＢＳＲＦ利用同步辐射单色光进行的全反射Ｘ－射线荧光实验，在单色能量为１０．１ｋｅＶ（高于Ｚｎ元素的Ｋ吸收边９．６６ｋｅＶ）下，测试了水标准样、生物标样（猪肝、桃叶）及其他试样（如人尿样等），得到了比较好（ｎｇ／ｇ级）的检出限。
The Total Reflection X-Ray Fluorescence experiment excited by monochromaticsynchrotron radiation is performed at the 4W1B beam line of BSRF. The energy of themonochromatic SR was 10. 1keV[just aboVe the K -edge energy of Zn (9. 66keV)].Severalstandard references including two kinds of waters, pig liver, peach leaves and several specimens (including two kinds of mineral water and human secretion) were tested. The minimumdetection limits (MDLs) of some elements are at the order of ng/g.For examples, the MDLsof Zn in the water standard reference GBW8608 and peach leaves standard reference are0. 68ng/g and 2. 27ng/g respectively.
