GB/T 35925-2018 Translated English of Chinese Standard. (GBT 35925-2018, GB/T35925-2018, GBT35925-2018): Determination of Impurity Fluorine Ion in Water Soluble Chemicals - Ion Chromatography Methodhttps://www.chinesestandard.net, 13 gen 2019 - 10 pagine This Standard specifies the ion chromatographic method for the determination of impurity fluoride ion (F-) content in the water-soluble chemicals. This Standard is applicable to the determination of fluoride ion content in water-soluble chemicals with fluoride ion content 400mg/kg. In this Standard, the quantitative limit of organic chemicals is 0.02mg/kg; while the quantitative limit of inorganic chemicals is 4.0mg/kg. This Standard is not applicable to the insoluble chemicals and the chemicals with main component containing fluorine. |
