現在,製定一种在含铼量低、含钼量高的样品中铼的定量測定法已有必要。要求此法的測定速度与精確性都高於現有的方法。现在製定的这种方法使铼的定量測定要迅速得多,而且將成為一种普遍的分析方法。新法与过去的蒸馏法不同,無須从酸溶液中蒸餾出铼,因為这是很困难的。含铼鑛石与溶液中一般都含有钼,它阻碍着铼的測定,钼呈金屬的有机化合物和乙基黃原酸鹽与铼分離,金屬的有机化合物用有机溶劑的混合物可自稀酸溶液中析出。到目前為止,主要有二种分析定铼法。席士凱与曼羅克法為使測定更為精確,利用醚提取法使已形成的色變濃,因而得到改善。霍甫曼与倫特尔法也有了改進。現在已製定含
Now it is necessary to develop a method for the quantitative determination of rhenium in samples containing low amounts of rhenium and molybdenum. Requires this method of determination of speed and accuracy are higher than the existing methods. The method now being developed makes the quantitative determination of rhenium much faster and will become a common analytical method. Unlike the old distillation method, the new method eliminates the need to distill rhenium from the acid solution, as it is very difficult. Rhenium ore and the solution generally contain molybdenum, which hinders the determination of rhenium, molybdenum metal organic compounds and ethyl xanthate and rhenium separation, metal organic compounds with a mixture of organic solvents can be diluted acid solution In the precipitation. So far, there are mainly two kinds of analysis methods for determination of rhenium. Hershey and Manrok method to make more accurate measurement, the use of ether extraction method so that the color has become rich, and thus be improved. Huofu Man and Renter law has also been improved. Has now been formulated
