摘要
采用原子吸收法直接测定牙膏中痕量铅，样品采用高温处理后用硝酸溶解。该方法基体干扰小，选择性好，灵敏度高，简便快速。
In this paper, the trace lead in toothpaste is determined directly with the atomic absorotion method and the samples are dissolved with HNO3 at high temperature. This method is of little disturbance. good selection. high sensitivity. and it is simple and fast.
