Standard Test Method for
Strontium Ion in Brackish Water, Seawater, and Brines1

This standard is issued under the fixed designation D 3352; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of the last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.

1. 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 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 exciting 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
