引言由于在水溶液中,氢比锗先在电极上析出,因此在水溶液中人们虽然经过各种尝试,但毕竟很难用电解法得到锗,曼塞尔斯等曾从非水溶液格林那试剂设法得到锗,但得到的是锗的化合物,由于锗的卤化物在各类有机化合物中溶解度都很大,因此可将锗的卤化物溶于有机溶剂、进行电解使锗析出。芬克和道格拉斯曾用GeI_4溶于各种有机溶剂中,得到各种不同的镀层,他们研究了析出的锗的量和电流密度的关系,齐格莱曾用GeCl_4溶于乙二醇中,进行了类似的实验。我们认为GeCl_4在非水溶液中的电解较之GeI_4更易推广,因为在实际工作总是将锗的化合物氯化成四氯化锗,然后进行提纯,但如果用乙二醇时,价格较贵且不易得。
INTRODUCTION Due to the fact that hydrogen is precipitated on the electrode earlier than germanium in aqueous solutions, it is difficult to obtain germanium by electrolysis after it has been tried variously in aqueous solution. However, Mansell et al. Germanium, but germanium compounds are obtained. Since germanium halides are highly soluble in various organic compounds, the germanium halides can be dissolved in an organic solvent and electrolyzed to precipitate germanium. Fink and Douglas have used GeI_4 dissolved in a variety of organic solvents, get a variety of coatings, they studied the amount of precipitated germanium and the current density relationship, Qi Geli used GeCl_4 dissolved in ethylene glycol, carried out A similar experiment. We think that the electrolysis of GeCl_4 in non-aqueous solution is easier to generalize than that of GeI_4 because in practice the germanium compounds are always chlorinated to germanium tetrachloride and then purified, but if ethylene glycol is used, it is more expensive and not readily available .
