摘要
以Ｐｄ（ＮＯ３）２－Ｔｒｉｔｏｎｘ－１００作为硒的基体改进剂，可使Ｓｅ的灰化温度从４００℃提高到１２００℃，吸光度增加２．９２倍．用Ｚｅｅｍａｎ效应背景校正法，有效地克服了共存物Ｆｅ、Ｐ等的干扰．检出限为０．１６ｎｇ，线性范围０．２～２．４ｎｇ，相关系数ｒ为０．
Pd(NO 3) 2 Triton x 100 was used as matrix modifier for the determination of selenium in traditional Chinese medicine injection.In this way the charring temperaturc can be incrcased by 400℃ up to 1200℃ and the absorbance can increase by 2.92 times.The interference of Fe P and other elements was reduced effectively by means of Zeeman effect background correction.The detection limit was 0.16 ng and the linear range was from 0.2～2.4 ng and r =0.993 1.
