引言由于二烷基汞化合物剧毒及其在汞的大气转移中起着重要的作用。因此很有必要建立一种快速,灵敏的测定二烷基汞化合物的分析方法,对于二烷基汞,特别是二甲基汞通常是加入HgCl_2或HgBr_2使之转化为电子捕获灵敏的甲基汞盐之后进行检定和测量。采用这种间接的分析方法遇到了一些困难。最常见的是衍生化的不充分。以及离析过程中萃取效率低,而使其分析的精度和准确度达不到要求。我们提出了一种新的反应气相色谱法(RGC)测定二烷基汞化合物。
INTRODUCTION The dialkyl mercury compounds are highly toxic and play an important role in the atmospheric transfer of mercury. Therefore, it is necessary to establish a rapid and sensitive analytical method for the determination of dialkylmercury compounds. For dialkylmercury, especially dimethylmercury, HgCl_2 or HgBr_2 is usually added to convert it into electron capture sensitive methylmercury After salt test and measurement. There are some difficulties with this indirect method of analysis. The most common is the lack of derivatization. As well as the low extraction efficiency in the isolation process, which can not meet the requirements of accuracy and accuracy of analysis. We propose a new reactive gas chromatography (RGC) for the determination of dialkylmercury compounds.
