Abstract
In this study atomic absorption spectrometry was employed for determination of the amount of lithium contained in sea salt brine produced by electrodialysis with ion exchange membranes and in bitten produced from the salt manufacturing process. In addition, observation was carried out on the interferences of diverse ions in the brine and the bittern, and on the effects of viscosity of the sample solution upon the determination of lithium.
After the raw sample solution was diluted. to an appropriate degree, the standard addition method was applied, and precise results were obtained without preliminary chemical separation. Lithium was found to be 0.92mg/liter in the brine, and 42.5mg/liter in the concentrated bittern, respectively.
These results indicated that the majority of lithium in sea water was concentrated into the brine and the bittern.
