This standard specifies a method for the determination of fluorine content in lithium carbonic acid using the Ion selective electrode method, which is suitable for the determination of fluorine content in lithium carbonic acid in the range of 0.0005% to 0.10%. Determination is performed by fluorine Ion selective electrode after analysis of the sample by nitric acid and adjusting the ionic strength under specific conditions using sodium citrate and potassium nitrate solutions. This standard describes in detail the selection and preparation of reagents, as well as the operation steps and precautions during the determination process.
