The behavior of the system Cd +2 /Cd(Hg) in the absence and presence of an aliphatic alcohol in noncomplexing media is analyzed in reciprocal derivative and double derivative chronopotentiometry with programmed current (RDCP and RDDCP, respectively). These electrochemical methods have been compared with derivative and double derivative voltammetry (DV and DDV, respectively). When the above system behaves as non reversible, it is not possible to establish a total analogy between chronopotentiometric and voltammetric responses, contrary to the case of a reversible process.
