| 摘 要： | 用氢化物发生－原子荧光光谱法测定了化工废水中的无机汞和总有机汞。无机汞可以直接测定;用过硫酸钾在沸水浴中加热20min即可把有机汞转化为无机汞,实现总汞的测定,二者之差为总有机汞。对影响测定灵敏度的一些实验参数进行了优化,汞的检测限为8．2ng/L。

| Abstract: | A sensitive method for the determination of inorganic mercury and total organomercury in chemical waste water by cold vapor generation atomic fluorescence spectrometry (CVG AFS) was proposed. Inorganic mercury was directly determined by CVG AFS. Organomercury was oxidized by potassium persulfate to its inorganic form prior to analysis. The difference between the two data was the value of total organomercury. Parameters affecting the sensitity in the process for the determination of mercury had been studied and optimized. Detection limit of mercury chloride was 8.2 ng/L. |
