2 1.2 samples containing from 0.1 to 70 000 mg/l of lithium, potassium, and sodium may be analyzed by this test method. Lithium, potassium, and sodium ions in brackish water, seawater, and brines by atomic absorption spectrophotometry1 this standard is issued under the fixed designation d3561 The number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision A number in parentheses indicates the year of last reapproval 1.2 samples containing from 0.1 to 70 000 mg/l of lithium, potassium, and sodium may be analyzed by this test method. Identification of a brackish water, seawater, or brine is determined by comparison of the concentrations of their dissolved constituents
The results are used to evaluate the water as a possible pollutant, or as a commercial source of a valuable constituent such as lithium Scope 1.1 this test method covers the determination of soluble lithium, potassium, and sodium ions in brackish water.
