摘要
利用溴离子对溴酸钾氧化荧光素的催化作用，建立了动力学荧光法测定微量Ｂｒ－的新方法，方法的检出限为１．９４×１０－２μｇ／ｍＬ，线性范围为６．０～１２．０μｇ／２５ｍＬ，将方法用于溴吡斯的明药片中Ｂｒ－含量的测定，结果满意。
Selenium in herbs of invigorating circulation blood and removing blood stasis was analysed by fluorometry.The RSD was less than 4 9%,the rate of recovery varied from 96% to 102%.The method has better selectivity.It is operated simply,and is suited for selenium of herbs analysis.
