The inhibition of Cd(II) reduction at the DME from aqueous 1 M NaClO4 by sucrose

It is shown that the steps in the earlier established CEE mechanism for the charge transfer process of Cd(II) reduction all are slowed down upon addition of sucrose. An attempt is made to correlate the individual standard rate constants with (i) the surface coverage by sucrose, and (ii) the viscosity of the solution layer adjacent to the electrode surface. No clear relationships are obtained, thus leaving the physical nature of the effects unexplained.
