| 摘 要： | 用活性炭对汞吸附富集，可测定汞浓度低于冷原子吸收法检出限的饮水水样．这种方法使汞被解析后，不经滤除活性炭而直接还原测定．平行样测定的相对偏差和加标回收率结果表明，该方法简便、实用．有较好的精确度和准确度

| Abstract: | The trace mercury in potable water sample was determined by using cold-vapouratomic absorption spectrometry after enriched by activated carbon. The mercury was desorptedfrom the activated carbon, and determined directly without filtration. The precision andaccurary of this method are comparatively high. These can be shown by repeateddetermination of the same water sample and by recovery test. |
