Methods for chemical analysis of lithium salts — Part 1: Quantitative determination of lithium hydroxide and lithium carbonate content in lithium hydroxide monohydrate — Potentiometric titration method

Scope

This international standard includes a method for the quantitative determination of lithium hydroxide (LiOH) and lithium carbonate (Li2CO3) in LiOH monohydrate (LHM). This method of determination is not suitable for LiOH anhydrous (LHA) because it rapidly absorbs CO2 from the atmosphere.
This method utilizes a potentiometric probe with an automatic titrator to measure both LiOH and Li2CO3 in the test solution. This approach is more efficient and precise than colorimetric approaches that rely mainly on manual operation and visual inspection.
