Title
Standard Practice for the Preparation of Substitute Ocean Water
ASTM International
Publication Date:
Sep 10, 1998
Scope:
This practice covers the preparation of solutions containing inorganic
salts in proportions and
concentrations representative of ocean water.
NOTE 1 - Since the concentrations of ocean water varies with sampling
location, the gross
concentration employed herein is an average of many reliable
individual analyses. Trace elements,
occurring naturally in concentrations below 0.005 mg/L, are not
included.
This practice provides three stock solutions, each relatively
concentrated but stable in storage.
For preparation of substitute ocean water, aliquots of the first two
stock solutions with added
salt are combined in larger volume. An added refinement in adjustment
of heavy metal concentration
is provided by the addition of a small aliquot of the third stock
solution to the previous
solution.
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.
