五十年代末期,在日本等国由于甲基汞的污染而发现的水误病或某些鸟类绝迹的现象,引起了人们的广泛重视,成为世界注目的一个中心。在测试技术方面,自1966年分别在瑞典和日本发表了用气相色谱测定甲基汞的方法以来,现在虽已有许多改进,但对泥中甲基汞的测定,一般都要经过重复萃取,操作冗长,而且在连续萃取过程中,不可避免要造成甲基汞的损失,至使回收率降低(一般为80％左右)。所以,如何寻找出既简便快
In the late 1950s, the water mistaken disease or the disappearance of certain birds found in Japan and other countries due to the pollution of methylmercury caused widespread concern and became a center of attention in the world. In terms of testing techniques, since 1966, the methods for the determination of methylmercury gas by gas chromatography have been published in Sweden and Japan. Although many improvements have been made nowadays, the determination of methylmercury in mud is generally subject to repeated extraction, The operation is lengthy and the methylmercury loss inevitably results in continuous extraction, leading to a reduction in recovery (typically around 80%). So, how to find out is easy and quick
