Chronopotentiometric Studies at Solid Electrodes

Anodic Voltammetry to +2.0 Volts. Application to Hydrocarbons and Oxidation Stability Studies

“…Oxidizability Indez (Ox.In.) = j /2 j log ipj X A/A' X C/C (1) where C is the concentration and A is the electrode area under standard conditions for the correlation of oxidizability index with the stability of the oils. Factors C" and A' correspond to the concentration and electrode areas for conditions other than those used for the correlation.…”

Quantitative Anodic Chronopotentiometry at Platinum Electrode

“…A recent publication (1) describes the anodic chronopotentiometry of a number of aromatic amines and phenols at a platinum electrode and suggests application of this method to analysis of such compounds. Subsequent work by Voorhies and Furman (11,12) has demonstrated the applicability of quantitative anodic chronopotentiometry at solid electrodes to several organic compounds.…”

Direct Detection of Acidity, Alkalinity, and pH with Membrane Electrodes

“…Under ideal circumstances (when diffusion is the dominant mode of transport), the square root of this transition time is proportional to the labile and therefore titratable, ion concentration. The chronopotentiometry methodology was originally introduced with solid electrodes , and was mainly utilized for fundamental characterizations such as the determination of diffusion coefficients and, with ion-selective electrodes, of membrane concentrations . The protocol appears to be particularly promising as a readout principle for ion-selective membrane electrodes since these membranes possess adequate selectivity for the extraction of just one type of analyte ion.…”
