摘要：

The dependence of the current yield of the electrochemical production of ferrate(VI) by anodic oxidation of iron was measured as a function of the frequency of alternating current, superimposed on the direct current; the ratio of the ac amplitude to the dc current was 2.6:1 and the electrolyte was NaOH solution of a concentration of 560 g dm-3 at 20 and 30-degrees-C. The highest current yield was found at an ac frequency of 5 Hz.
