采用硝酸-双氧水体系及高压消解法处理陶瓷样品,利用原子荧光光谱仪测定了陶瓷样品中的汞,并对灯电流、负高压、还原剂等条件进行了优化。结果表明,RSD值仅为1.2%,回收率为91.9%～103.0%,检出限0.004μg/L,说明该方法精密度和灵敏度高,可作为陶瓷样品中痕量汞的检测方法。

The ceramics samples were digested under pressure with nitric acid and hydrogen peroxide. The method for the de- termination of Hgin ceramics has been developed by HG - AES. Many measure conditions including light electric current, negative high voltage, reducing agent, etc. were optimized. The results showed that value of RSD is 1.2%. The recovery rates of the method are in the range Of 91.9% - 103.0%. The detection limit of the method is 0. 004μg/L. This method has high sensitivity. This method is suite to determine Hg in ceramics.
