本文提出了环境空气中测定痕量氟的电极法新方案,由于用六甲基二硅胺烷予分离浓缩氟,所以本法克服了现行氟电极分析法的一些弱点与困难,在较短时间内测得准确可信的数据,当吸收液含氟量超过0.5μg,则空气中的氟含量均可被测出,因为予分离基本除净铝、铁等干扰性金属与非金属元素,故本法适用的范围较广泛。本文还提出制取低气氟标的一种新途径,现行各种气氟采样方式的可行性似仅靠经
In this paper, a new electrode method for the determination of trace fluorine in ambient air is proposed. Due to the separation and concentration of fluorine with hexamethyldisilazane, this method overcomes some of the weaknesses and difficulties of the current fluorine electrode assay. In a relatively short time Accurate and reliable data measured inside, when the absorption liquid fluorine content of more than 0.5μg, the fluorine content in the air can be measured, because the pre-separation of the net except for aluminum, iron and other non-metallic and non-metallic elements, so The scope of application of this Law is wider. This paper also proposed a new way to produce low-fluorine standard, the feasibility of the existing gas-fluorine sampling methods only relies on
