Description

To know the constituents of photographic developers, the method of paperchromatography was employed for the separation and identification of developing agents. As an apparatus, Paperchromatographic Cylinder Model B (Toyo-Roshi Co.) was used. Solvents as chromatographic developers are composed of “n-butanol”, acetic acid (glacial) and water, mixed in the volume proportion 4 to 1 to 5, and “ethylacetate”, acetic acid (glacial), and water, mixed in the volume proportion 4 to 1 to 2, from which the organic layer is separated after shaking, and used. As spray reagent, a 2% solution of ammoniacal silver nitrate was used. And paper used is Toyo filter paper No.50 (2cm×40cm).<BR>From chromatograms, Rf-values of the known developing agents were calculated. And we compared these chromatograms with those of unknown samples. Microdol, Promicrol, Atomal, Atofin, Mikrolin etc, were employed, as unknown samples.
