Standard Specification for Substitute Ocean Water
|Publication Date:||28 November 1975|
|ICS Code (Water of natural resources):||13.060.10|
This specification covers the preparation portions and concentrations representative of ocean water.2
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 ppm. are not included.
This specification 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.
