- 中文摘要: Anodic deposition and cathodic stripping of bromide at varying concentrations in 0.1N KNO3 medium at silver electrode was studied by constant current method. The apparent coulometric efficiency could be explained with Laitinen’s model. Modified Tafel plots were given and the transfer coefficient, α, was calculated to be 0.5 for the reversible anodic step. Two distinct steps in anodic deposition of bromide were definitely observed. Reduction of oxygen with low current density in 0.1 N KNO3 and at silver electrode was examined and was found to do no harm if deaeration was done by Meites technique. Constant current potentiometry model was proposed to explain the potential concentration relation.
