5.1 This test method4 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. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered 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. Summary of Test Method
4.1 This test method is dependent on the fact that metallic elements, in the ground state, will absorb light of the same wavelength
they emit when excited. When radiation from a given excited element is passed through a flame containing ground state atoms of
that element, the intensity of the transmitted radiation will decrease in proportion to the amount of the ground state element in the
3
flame. A hollow cathode lamp whose cathode is made of the element to be determined provides the radiation. The metal atoms
to be measured are placed in the beam of radiation by aspirating the specimen into an oxidant-fuel flame. A monochromator isolates
the characteristic radiation from the hollow cathode lamp and a photosensitive device measures the attenuated transmitted
radiation.
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
