Abstract
Способ регенерации фиксажно-отбеливающего раствора, включающий катодную обработку раствора на проточном объемно-пористом электроде, состоящем из углеродного волокнистого материала и обработку на аноде, отличающийся тем, что фиксажно-отбеливающий раствор дополнительно подвергают катодной обработке на проточном объемно-пористом электроде из металлизированного синтепона и после этого анодной обработке на проточном объемно-пористом электроде из углеродного волокнистого материала, причем в процессе катодной обработки с использованием только проточного объемно-пористого электрода из углеродного волокнистого материала, отделенного от противоэлектрода катионнообменной мембраной, в наиболее нагруженной точке электрода поддерживают потенциал положительного начала выделения металлического серебра и фиксируют количество электричества затрачиваемого на восстановление Fe, во время катодной обработки с использованием только проточного объемно-пористого электрода из металлизированного синтепона, отделенного от противоэлектрода катионнообменной мембраной, в наиболее нагруженной точке электрода поддерживают потенциал, соответствующий предельному току восстановления серебра, а в процессе третьей, анодной, обработки с использованием только проточного объемно-пористого электрода из углеродного волокнистого материала, отделенного от противоэлектрода катионнообменной мембраной, в наиболее нагруженной точке электрода поддерживают потенциал, соответствующий предельному току окисления Feи при этом затрачивают такое же количество электричества, что и при катодной обработке фиксажно-отбеливающего ра�A method for regenerating a fixative-bleaching solution, comprising cathodic processing of the solution on a flow-through volume-porous electrode consisting of a carbon fiber material and processing on the anode, characterized in that the fixation-bleaching solution is further subjected to cathodic processing on a flow-through volume-porous electrode from a metallized synthetic winterizer and then anodic processing on a flow-through volume-porous electrode of carbon fiber material, and in the process of cathodic processing using m only a flow-through volume-porous electrode of carbon fiber material separated from the counter electrode by a cation-exchange membrane, at the most loaded point of the electrode, the potential for the positive onset of silver metal release is maintained and the amount of electricity spent on Fe recovery is recorded during cathodic processing using only flow-through volume-porous electrode of a metallized synthetic winterizer, separated from the counter electrode by a cation exchange membrane, in the most The potential corresponding to the limiting current of silver recovery is maintained at the loaded point of the electrode, and during the third, anodic processing using only the flow-through volume-porous electrode of carbon fiber material separated from the counter electrode by a cation exchange membrane, the potential corresponding to the limiting limit is maintained at the most loaded point of the electrode in this case, the same amount of electricity is consumed by the Fei oxidation current as during cathodic treatment of the fixer-bleach
