摘要
本文用石墨炉原子吸收法对岩石土样中Ｓｂ的测定方法进行了研究。对工作条件、测定酸度、涂层管，共存离子的干扰与消除、回收及精密度等进行了实验。采用Ｎｉ作为基体改进剂可以消除干扰元素对Ｓｂ的影响。此方法的回收率和精密度比较满意。
The following experiments have been finished: working condition; determination acid; tuceng coat tube; interference elimination; recovery and percision ect. The interference could be elimination by added Ni to the sample.The detection limit of the method is 1 × 10--9g/ml. Reccovery is 92. 2--97. 3%.The precision were satissfactory.
