Abstract
In this study, amounts of titanium contained in sea water, biomaterials and sediments were determined by a method using tiron (disodium-1, 2-dihydroxybenzene-3, 5-disulfonate).<BR>Ferric iron was added to slightly acidified sample solution as a carrier for titanium, and pH was adjusted to 8.5-9.5 with ammonia. Ferric hydroxide was filtered and dissolved in sulfuric acid. The major portion of iron was removed by mercury cathode electrolysis, and then the absorbance of titanium-tiron complex formed at pH 4 in the presence of EDTA, was measured at 420 mμ.<BR>After analyzing sea water and lake water samples, several kinds of biomaterials such as seaweed or shellfish, and sediments, the following results were obtained: The content of titanium in sea water amounted to approximately 2μg/l, and that in several kinds of shellfishes and seaweeds amounted to 2.5-6.9×10-2% and 2.5-6.5×10-8% in ash samples, respectively. The titanium content in marine sediments was of the order of 10-1%. In general, the sea samples contained less amount of titanium as compared with the similar land samples.
