Standard Test Method for
Barium in Brines, Seawater, and Brackish Water by DirectCurrent Argon Plasma Atomic Emission Spectroscopy1

This standard is issued under the fixed designation D 3986; 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 dissolved
and total recoverable barium in brines, seawater, and brackish
waters by direct-current argon plasma atomic emission spectroscopy (DCP–AES).

1.2 This test method has been tested in the range from 10
mg/L to 20 mg/L. Samples shall be diluted to contain concentrations within the calibration range (see 11.1 and 12.5). Higher
concentrations can also be determined by changing to a less
sensitive emission line.

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.
