同步辐射X射线荧光光谱及应用

X-ray Fluorescence Spectrometry Using Synchrotron Radiation and its Application

一、同步辐射光由于常规X射线源(如:X-光管;放射性同位素)的强度低,散射背景高,使得X射线荧光光谱(XRF)法的检测限不如其他一些方法低。借助于化学预富集(如:共沉淀,萃取,离子交换…),检测限虽下降1~2个数量级,却牺牲了其他方面的优点。

The synchrotron radiation(SR)from an electron storage ring is very attractive as a new x-ray source for x-ray fluorescence analysis(XFA).The experimental arrangment and application instances of SRXFA were reviewed.
