摘要
采用氢化物原子荧光光谱法测定了电石法生产PVC树脂中汞的含量,该方法回收率高,精密度好。在不同的加标水平下,其回收率为90.54%~96.88%,相应的RSD值均小于6%。该方法完全适用于电石法生产PVC树脂中汞残留量的测定。
The mercury content in PVC resins produced by carbide method was determined by hydride atom fluorescence spectrum. This method had the characteristics of high recovery and good precision. Under different sample level, the recovery was 90.54 % - 96.88 %, and the corresponding RSD was less than 6%. This method was suitable for the determination of residual mercury content in PVC resins produced by carbide method.
