Abstract

Infrared spectra of LiOH and Li//2CO//3 suspended on KBr discs were measured over the concentration range 20 mu g/100 mg KBr to 600 mu g/100 mg KBr. The absorbance of a selected infrared band for each sample was carefully determined. The empirical equation, which expresses a correlation between the absorbance and the concentration, was given for each lithium compound. The feasibility of independent and direct determination of the LiOH and Li//2CO//3 content in Li//2O was shown, and the spectroscopic technique was applied to a typical Li//2O sample. It was shown that the detection limit of the analysis was improved by low-temperature measurements of the infrared spectra.
