Some Factors Affecting the Precision of Polarographic Half-Wave Potential Measurements
نویسنده
چکیده
The experimental conditions required for the precise determination of polarographic half-wave potentials have been investigated and are discussed. The values of half-wave potentials vary with the characteristics of the dropping-m ercury electrode in the case of reduction of m etal ions to metal soluble in mercury. Consequently, it is necessary to specify the experimental condition whenever values for half-wave potentials are reported. ~With proper precautions it is possible to attain reproducibility within ± 0.2 millivolt in the meas urements.

A Potential Method for Body and Surface Wave Propagation in Transversely Isotropic Half- and Full-Spaces
The problem of propagation of plane wave including body and surface waves propagating in a transversely isotropic half-space with a depth-wise axis of material symmetry is investigated in details. Using the advantage of representation of displacement fields in terms of two complete scalar potential functions, the coupled equations of motion are uncoupled and reduced to two independent equations...

The aqueous electrochemistry of a number of anthraquinone derivatives was studied by using cyclic voltammetry at the surface of carbon paste electrode (CPE). From measurements of the half-wave potential as a function of pH, the potential - pH diagrams were constructed for each compound. The values of formal potentials and the pK'a of some different redox and acid-base couples inv...

Kalman filtering was applied to the current vs. time data obtained at the growing mercury drop of a DME under d.c. polarographic conditions, to separate the faradaic and capacitive components of the electrode current. Polarograms consisting of the pure faradaic current vs. applied d.c. potential were subjected to a four-parameter curve-fitting procedure to obtain the polarographic characteristi...

Potentiometric pKa and polarographic behaviour of I ,3-indandione-monoxime-2-phenyl azo and four of its substituted derivatives were investigated in buffer solution of pH -2-12. The results showed that the compounds are in the azo-form, where its reduction wave precedes that of the oxime. A mechanism for the electrodic processes was proposed. Half-wave potentials showed fair correlation with Ha...
