摘要：

The kinetics of the oxidation of Cu(I) by Fe(III) in HCl solutions were studied electrochemically. A rotating ring disk electrode was used, and rigorous corrections were made to the ring current to account for overlap of the Fe(II)/Fe(III) and Cu(I)/Cu(II) couples. The rate was first order in both [Cu(I)] and [Fe(III)] and also depended on [Cl-]T2and inversely on [H+]. A mechanism with two parallel reaction paths is proposed to account for these observations. The activation energy of the reaction is 86.4 kJ/mol. © 1990, American Chemical Society. All rights reserved.
