本文探索了KBr的定影性能并与海波定影刑进行了比较。实验表明:KBr定影剂定影速度不如海波定影剂,但其定影速度可以通过高温度来提高,而且KBr定影剂定影的胶片其宽容度优于海波定影剂,二者其它性能相近。采用KBr定影剂可望通过稀释、过滤回收AgBr,然后浓缩可使定影剂再生,或简单电解回收Ag及Br_2并使定影剂再生。 This article explores the fixing performance of KBr and compares it with the Hypothesis. Experiments show that the fixing speed of KBr fixer is not as good as Haibo fixer, but its fixing speed can be improved by high temperature. And the KBr fixing fixer has better tolerance than Haibo fixer, and the other properties are similar. KBr fixer is expected to dilute, filter recovery of AgBr, and then concentrate the fixer can be regenerated, or simply electrolytic recovery of Ag and Br_2 and the fixer regeneration.
