GB/T 11064.1-2013 Methods for chemical analysis of lithium carbonate, lithium hydroxide monohydrate and lithium chloride - Part 1: Determination of lithium carbonate content - Acid-alkali titrimetric method 1 Scope This part of GB/T 11064 specifies the methods for determination of lithium carbonate content in lithium carbonate. This part is applicable to the determination of lithium carbonate content in lithium carbonate, within a range of over 95.00%. 2 Method summary A test portion is dissolved in a certain amount of water. With methyl red-bromocresol green as the indicator, the total alkalinity of the test portion to be titrated with the hydrochloric acid reference titration solution, and the lithium carbonate content is calculated by the consumed hydrochloric acid reference titration solution. The calcium content in the test portion shall be converted into the lithium carbonate content and subtracted from the calculated results. 3 Reagent Unless otherwise specified, analytical reagents and deionized water shall be used for the purpose of this part. 3.1 Methyl red-bromocresol green indicator: take 30mL of bromocresol green solution (3.1.1) and 10mL of methyl red solution (3.1.2) and mix them well. 3.1.1 Bromocresol green solution: weigh 0.1g of bromocresol green and dissolve it in 100mL of ethanol (95%) solution. 3.1.2 Methyl red solution: weigh 0.2 g of methyl red and dissolve it in 100 mL ethanol (95%) solution.
