Interference of sodium was measured for the determination of micro quantity (2μg cm-3) of lithium in the solution containing sodium nitrate or sodium chloride by atomic absorption spectrophotometry and flame photometry with air-acetylene flame. A solution containing lithium of 2μg cm-3 in 0.1 M nitric acid was used as a reference solution, because the depression in nitric acid was within experimental error (<1%) in a range of (0.050.5)M in the preliminary experiment for the effect on the signal of lithium in nitric, hydrochloric, and perchloric acid. For atomic absorption spectrophotometry no interference was observed in a range of (0.257)μg cm-3 of sodium concentration, while the enhancement of (25)% was measured for (251000)μg cm-3 and the increased depression at higher concentration than 1000μg cm-3. Less depression was noticed in sodium nitrate solution. Similar interference was observed in the systems of the various acid and salt solutions by flame photometry.
