| 摘 要： | 鉴于汞冷原子吸收光度法测定汞的高灵敏度，提出了一种间接地测定水中痕量氰化物的新方法。由于汞与ＣＮ－能生成稳定的络合物，处于化合态的汞不再被还原为原子态的乘，因而，可在不经分离的情况下，用汞冷原子吸收光度法测定剩余的汞，从而求出氰化物的含量．方法经实验证明，灵敏度高，重现性好，快速简便。

| Abstract: | This Paper introduced the indirect determination oftrace cyanide in water by coal mercury atom absorption.Because Hg and CN- can combine into a stable complexCompound, which can't be reduced, the cyanide contentcan be determined by determing surplus mercuxy usingcoid atomic absorption without seperation, The experiment showed that the method was sensitive, sample andreappearable. |
