The extraction of platinum. palladium and rhodium by N_(1923) was investigated.

在盐酸介质中伯胺在低酸度下可近于定量地萃取铂与钯,但对锗的萃取则不能令人满意。铑在盐酸中以配阴离子存在,理应易以离子对缔合形式为胺类萃取,故其萃取率很低令人费解。国产长链仲碳伯胺N_(1923)是含19~23个碳原子的伯胺的混合物,与国外的Primene-JMT相当,主要用于钍的萃取,对贵金属的萃取未见报道。本文研究了N_(1923)在盐酸中对铂、钯和铑的萃取,并初步探讨了其萃取机理。

This paper describes the solvent extraction of germanium from the leached solution of uranium- and germanium-containing lignite ash. Both decylhydroximic acid and trifatty amine are presented as extractants of germanium. The extraction and stripping rates of germanium, and its solubility in Water are determined. The results indicate that the extraction capacity of decylhydroximic acid is strong and the phase disengagement is quick, and the germanium can be extracted in a larger range of acidity. The tartaric...

This paper describes the solvent extraction of germanium from the leached solution of uranium- and germanium-containing lignite ash. Both decylhydroximic acid and trifatty amine are presented as extractants of germanium. The extraction and stripping rates of germanium, and its solubility in Water are determined. The results indicate that the extraction capacity of decylhydroximic acid is strong and the phase disengagement is quick, and the germanium can be extracted in a larger range of acidity. The tartaric acid should be needed, when the trifatty amine is used for extracting germanium. When the mole ratio of H4C4O6to Ge is 4, the extraction of germanium is high.

本文叙述了从含铀锗褐煤灰的浸出液中萃取锗的研究。通过不同萃取剂的筛选,提出了癸基异羟肟酸和三脂肪胺两种萃取锗的萃取剂。测定了锗的萃取率、萃取剂的水溶性、锗反萃取率等。结果表明,此两种萃取剂都能完成从含锗溶液中萃取锗的要求。癸基异羟萃酸肟取锗的能力强、分相快,能在较大酸度范围内萃取锗。用三脂肪胺萃取锗需加入酒石酸,当H_4C_4O_6/Ge摩尔比为4时,锗的萃取率较高。

A very sensitive and selective flotation-spectrophotometric method for the determination of microamounts of Ge based on Ge-o-chlorophenylfluorone system has been investigated. The Ge complex is flotated with cyelohexane (plus iso-amyl acetate) and dissolved in alcohol, The Sandell sensitivity is 0.000483μg/cm~2 at 520nm. The method has been applied to the determination of microamounts of Ge in coal fly ash.

本文提出了一个灵敏度高,选择性好的测定微量锗的萃取浮选吸光光度法。它是基于Ge与o—Cl—PF形成配合物后被环己烷(加醋酸异戊酯)浮选,然后溶于乙醇中,配合物在波长520nm处,其摩尔吸光系数为ε=1.5×10~5L·mol~(-1)·cm~(-1),此法可以直接用于煤样中微量锗的测定。
