(Test Method)Standard Test Method for Strontium Ion in Brackish Water, Seawater, and Brines
Standard Test Method for Strontium Ion in Brackish Water, Seawater, and Brines
SIGNIFICANCE AND USE
This test method can be used to determine strontium ions in brackish water, seawater, and brines.
SCOPE
1.1 This test method covers the determination of soluble strontium ion in brackish water, seawater, and brines by atomic absorption spectrophotometry.
1.2 Samples containing from 5 to 2100 mg/L of strontium may be analyzed by this test method.
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

4.2 Since the variable and sometimes high concentrations of matrix materials in the waters and brines affect absorption
differently, it is difficult to prepare standards sufficiently similar to the waters and brines. To overcome this difficulty, the method
of additions is used in which three identical samples are prepared and varying amounts of a standard added to two of them. The
three samples are then aspirated, the concentration readings recorded, and the original sample concentration calculated.
