测定汞的方法有很多报导,据资料[1]报导在醋酸——醋酸钠缓冲溶液中用硫代米蚩酮与汞生成红色络合物,能直接测定微克量的汞,实验证明该方法能测定0.0001％以上汞的含量。 用热逐法熔矿几乎可以把所有干扰元素分离,同时逸出的有少量砷、锑、硫,加入活性炭可抑制其挥发,即不干扰测定。所以本法不存在干扰元素的问题。此法可用于常量汞的测定,也可用于化探试样微克量汞的测定。方法简单快速,易于掌握。
Methods for the determination of mercury are widely reported. According to the data [1], it has been reported that the red complex formed with thiomorpholide and mercury in acetic acid-sodium acetate buffer solution can directly measure micrograms of mercury. Experiments show that this method can The content of mercury above 0.0001% was measured. With the law by hot legumes almost all interfering elements can be separated, while escaped with a small amount of arsenic, antimony, sulfur, adding activated carbon can inhibit its volatility, that does not interfere with the determination. Therefore, this law does not exist the problem of interfering elements. This method can be used for the determination of mercury, but also for the determination of micrograms of mercury in geochemical samples. Method is simple and quick, easy to grasp.
