【摘要】 本文测定了八个照相染料在不同pH条件下的还原电位。发现其中一些增感染料的还原电位与其溶液的pH值无关,而一些减感染料依赖于pH值的变化。本文用染料质子化机理分析了这些结果。更多还原

【Abstract】 In this paper the reduction potentials of eight photographic dyes were measured. It was found that reduction potential of some cyanine dyes are independent of pH, whereas that of desensitizing dyes are pH-dependent. These results were discussed in terms of the protonation mechanism of dyes.更多还原
