“…which is obtained by adding a correction term< 12 ) due to spherical geometry of the electrode to the Randless-Sevcik equation for a plane electrode< 2 for reduction of Ni(ll) to Ni at various temperatures Figure 7 shows the relationship between the concentration of Ni(II) and the peak current observed at an electrode area of 5.4 mm 2 and a scan rate of 0.1 V /s. The peak current increased linearly with the concentration of Ni(II) up to 2 X 10' 2 mol/dm 3 .…”

“…5). In their approach, the measured current is described as the sum of two currents: the current generated via linear diffusion from an area corresponding to the surface of the spherical electrode flattened into a plane, and a hemispherical correction term which was proposed by Reinmuth [33].…”

Voltammetric Determination of Diffusion Coefficients in Polymer Membranes: Guidelines to Minimize Errors

Diffusion coefficients are important in the design, optimization, and selection of membranes used in many applications including chemical and biosensors. Since the diffusion‐controlled transport of the analyte and interfering ions and molecules through polymer membranes may affect the rate of response, detection limit, selectivity, lifetime, etc. of chemical and biosensors, having a rapid and accurate method for the determination of diffusion coefficients of different compounds in a variety of membranes is uniquely important. In our contribution, we present a simple protocol for the rapid determination of the diffusion coefficients of electrochemically active analytes by linear sweep voltammetry. The expected errors in the estimated coefficients have been analyzed through modeling and the correlation between the magnitude of the unknown diffusion coefficients and the method's related maximum error is presented as a contour plot for different working electrode dimensions. It is also shown that our analysis protocol can be used to estimate the diffusion coefficient in complex membrane matrices and non‐ideal experimental conditions with a maximum systematic error of 14 % even without any experimental parameter optimization.

“…The experiments with the quartz oscillator in contact with the n-C4El/H20 mixture of non-critical composition show that the value of the slope of the Af versus [(qe)y' -( q~) y ?~,~] curve is smaller by a factor of 2.5 than that calculated on the basis of the Kanzawa-Gordon equation. It is known that in C4E1/H20 mixtures of non-critical ( y > 0.1) [2,5] and critical composition there exist micellar like structures. It is possible that these structures in combination with the large value of the shear gradient produced by the quartz oscillator cause the unusual small value of a.…”
