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》 Related products

This standard specifies a method for the determination of the amount of lithium carbonic acid in lithium carbonic acid, which is applicable to samples with a lithium carbonic acid content greater than 95.00%. Methods The total alkalinity (TA) of the sample was titrated with muriatic acid standard solution by dissolving the sample in water, using methyl red-bromocresol green as an indicator. The content of lithium carbonic acid was calculated by measuring the amount of muriatic acid consumed. At the same time, the content of calcium in the sample needs to be converted into the lithium carbonic acid content and deducted from the calculation result. The standard requires the use of analytical pure reagents and deionized water to ensure the accuracy of the determination.
