二甲基汞的水解规律及富集方法

STUDY ON THE HYDROLYTIC BEHAVIOUR AND PRECONCENTRATION OF DIMETHYL MERCURY

对二甲基汞在盐酸介质中水解为氯化甲基汞的规律进行了详细研究。结果表明,经过约一天半的时间二甲基汞在酸性介质中可完全水解为氯化甲基汞,利用此特点提出对痕量二甲基汞进行间接富集的方法。

It is found that (CH_3)_2Hg is totally transformed into CH_3HgCl in a medium of 2mol ·L ' HC1 and 1.0×10^(-4)mol ·L^(-1) Na_2S_2O_3. A new method for the preconcentration of traces of (CH_3)_2Hg is given based on the above mentioned behavior.
