本文用改进的Reinders方法研究了硫、金和还原敏化的感光乳剂在化学成熟过程中敏化中心平衡电极电势的变化,并对这些感光乳剂层内敏化中心的抗氧化性进行了比较研究。 实验结果表明:在化学成熟过程中,敏化中心的平衡电极电势的变化与感光层光敏度的变化趋势极为相似。金敏化乳剂中,在化学成熟最佳时生成的敏化中心比成熟初期生成的敏化中心不易氧化。还原敏化产生的敏化中心较稳定。文中根据的化学敏化理论对实验结果进行了讨论。
In this paper, the modified Reinders method was used to study the changes of the potential of the balance electrode in the sensitization center of sulfur, gold and sensitized emulsion sensitized with reducing sensitizer. The antioxidant activity of sensitizing centers in sensitizing emulsions was also compared . The experimental results show that during the process of chemical maturation, the change of the equilibrium electrode potential at the sensitization center is very similar to that of the photosensitivity. In the Jin Minhua emulsion, the sensitized center formed at the best of chemical maturation is less oxidized than the sensitized center formed at the beginning of maturity. Sensitization center produced by the reduction of sensitization more stable. In this paper, the experimental results are discussed based on the theory of chemical sensitization.
