| Abstract: | The fluorine obtained by electrolysis method contains impurities such as nitrogen, hydrogen fluoride, carbon tetrafluoride, and so on. The carbon tetrafluoride content could be determined by common gas chromatography after replacing chlorine in sodium chloride using fluorine and absorbing the chlorine using NaOH aqueous solution. This method is safe, rapid and easy to operate. |
