一、前言: 鎵的出色測定法在不少的文献中已有成功的記述,不过大量鉄中少量鎵的分离法还是值得探討的。虽可用氫氧化鈉分离鉄和鎵,但由于产生严重的吸附現象,得不到滿意的結果。我們还看到采用离子交換法和色层法进行分离,伹对于大量鉄存在时不尽适合,因而最常采用的方法还是6N盐酸用乙醚萃取。但我們分析的对象是炼鍺廢液,含鉄量竟达0.02—0.05g/ml,还原时耗費大量三氯化釱,造成經济上的浪費,同时終点
First, the foreword: The outstanding determination of gallium in many literatures have been successfully described, but a large number of 鉄 in a small amount of gallium separation method is worth exploring. Although sodium hydroxide can be used to separate gallium and gallium, satisfactory results have not been obtained due to the severe adsorption phenomena. We also see separation by ion exchange and chromatography, which is not suitable for the presence of large amounts of gallium, so the most commonly used method is 6N hydrochloric acid, which is extracted with ether. However, our analysis of the object is refining germanium waste, containing as much as 0.02-0.05g / ml, reduction cost a lot of trichloride, resulting in economic waste, while the end
