本文应用旋转铂电极测定了照相助剂苯取代物中邻苯二酚、间苯二酚、对苯二酚和邻苯二胺的氧化还原电位值(E_(ox)/Red),苯取代物的加入,由于它们的E_(ox)/Red值的不同,能影响AgX乳剂的灰雾密度及其感光度。试验部分一仪器与试剂图1是应用旋转铂电极测定照相助剂氧化还原电位的线路示意图。在图1中1为电子交流稳压器,其 In this paper, the redox potential (c / e) of catechol, resorcinol, hydroquinone and o-phenylenediamine in photographic aids were determined by rotating platinum electrode. Due to their different E_ (ox) / Red values, can affect the fog density of the AgX emulsion and its sensitivity. Experimental part of an instrument and reagent Figure 1 is a schematic diagram of the determination of redox potential of the photocatalyst using a rotating platinum electrode. 1 in Figure 1 for the electronic exchange regulator, which
