Artificial seawater – Wikipedia
The substitute ocean water with heavy metals, prepared in accordance with Section 7, will have the complete composition shown in Table X1.
Add mL of Stock Solution No. Adjust the pH to 8. Only a few millilitres of NaOH solution should be required.
Sodium bicarbonate NaHCO 3. Steady-state growth and ammonium uptake of a fast-growing marine diatom Archived at the Wayback Machine. For preparation of substitute ocean water, aliquots of the first two stock solutions with added salt are combined in larger volume.
Examples are for tests on oil contamination, detergency evaluation, d1141-988 corrosion testing. Artificial seawater is primarily used in marine biology and in marine and reef aquariaand allows the easy preparation of media appropriate for marine organisms including algaebacteriaplants and animals.
The pH after adjustment with 0. Webarchive template wayback links Articles with short description. Typically, laboratory grade water is used when making synthetic salts . Last previous edition approved in as D —98e1. Where d1141-98 is involved, the results obtained from laboratory tests may not approximate those secured under natural testing conditions that differ greatly from those of the laboratory, and especially where effects of velocity, salt atmospheres, or organic constituents are involved.
