The determination of lithium in urine by flame photometry after separation by ion exchange chromatography.
An ion exchange method is described for the determination of lithium ions in urine. The lithium ion is separated from interfering substances on a strong cation exchange resin by elution with hydrochloric acid, 0.5 mol/l. The concentration of lithium in the eluate is determined by flame photometry.
