Studies on Analytical Methods of Photographic Materials (II)

Microseparation and Determination of Organic Addition Agent in Photographic Developer

Abstract

In the previous report, addition agents (6-nitrobenz-imidazole, Benztriazole) were separated from Phenidone-Hydroquinone developer by paper-chromatography and determined photometrically.
Now instead of paper, cellulose ion exchanger adsorbent column was employed in this analysis. The micro quantitative separation and photometrical determination method of addition agent in Phenidone-Hydroquinone and their oxides mixture was described.
Adsorption and desorption behavior of addition agent against to cellulose ion exchanger adsorbent column was explained by paper electrophoretic value of each addition agent.
By the use of DEAE-OH^-, -OAC^-, -Cl^- and SE-H⁺ columns, five sorts of anti-fog andanti-bronzing agents were found to be very favorable from photographic developer. The standard deviation of this experiment was 1 % and less, resulted from usual addition range.
