“…peaks. So far, silica gel column chromatograph has been mainly employed to determin organic acids in an aquatic environmen (MUELLER et at., 1958;KOYAMA and THC MPSON, 1964;KAMATA, 1966). This prc cedure, however, is time consuming an has a low sensitivity in the determinatio of organic acids as shown in Table 2.…”

“…Silica gel chromatography (MUELLER et al, 1958;KOYAMA and THOMPSON, 1964;KAMATA, 1966) and paper chromatography (WEINMANN, 1970) were applied to separate several species of volatile organic acids. These methods, however, are accompanied by some disadvantages, because a large volume of sample waters is needed to conduct qualitative and quantitative analysis of these organic acids.…”

RESNIK, LEE, and POWELL (1955) used tertiary-butyl alcohol instead of n-butyl alcohol to make the end-point of the titration sharper and also to prevent the possibility of ester forma-tion, which is likely to occur on the column.…”

: It is well known that the organic compounds, particularly carbohydrates, are fermented to volatile fatty acids in significant quantities under anaerobic conditions. There were, however, up to date not so many reports on the extraction and determination methods of organic acids in sea water and marine sediments.Then, the purpose of this work was focussed to study the methods for the extraction and also for the quantitative analysis of organic acids in sea water and marine sediments.The following results were concluded from the studies.( 1 ) The volatile fatty acids were quantitatively recovered with the silica gel chromatographic method using benzene-n-butyl alcohol (20%) as an eluting solvent.( 2 ) The organic acids added in the marine sediment were 87 to 90 per cent recovered by the three or four water extractions.( 3 ) The organic acids in sea water and in the extract of sediment were quickly extracted by 4 or 8 hour extraction with the continuous ether extractor presented in this paper.The present analytical method may have the advantages of higher accuracy and less time consumption than the other methods for determining organic acids in sea water and sediments.
