测定铍中氟的含量,不仅有助于了解其纯度,指导铍的冶金生产设计,且由于铍的特殊用途,故与能源开发也密切相关.现在,一般采用水蒸汽蒸馏分离(即W-W法)后的直接、间接比色法、硝酸钍容量法或电极法.这类方法颇费时、耗能较多,且有的准确度、精密度亦不甚理想.Taves建议用六甲基二硅醚(Hexa-methyldisiloxane即HMDS)作氟自然扩散的分离试剂,其后Yoshida等人提出通氮来加
Determining fluorine content in beryllium not only helps to understand the purity of the beryllium, but also guides the metallurgical production design of beryllium, and is also closely related to the development of energy due to the special use of beryllium.Nowadays, steam distillation separation (WW method) After the direct, indirect colorimetry, thorium nitrate capacity method or electrode method.This method is time-consuming, more energy consumption, and some accuracy, precision is not very satisfactory .Taves recommended hexamethyldisiloxane (Hexa-methyldisiloxane that is HMDS) for the natural diffusion of fluorine reagent, followed by Yoshida et al proposed nitrogen to Canada
