Five methods of isolating organic materials from salt solutions are evaluated for applicability in separating organic and inorganic constituents of sea water. A C14-labeled aged algae culture was used as a test solution to determine the effectiveness of various methods of isolating total dissolved organic material. Organic compounds, known to be involved in biological metabolism, were also added to natural sea water to determine the effectiveness of various methods in isolation....
