Voltammetric oxidation of solution and solid phases of salts of (V/(CO)6-) in aqueous (electrolyte) media

Article Abstract:

Research was conducted to examine the voltammetric oxidation of solution and solid phases of salts of (V/(CO)6-) in aqueous (electrolyte) media. The starting material was sodium diglyme and stabilized salt and experiments were confined to the potential region associated with the process. Results indicate that V(CO)6 in solution reacts with water as well as with oxygen. However, the product of electrochemical oxidation reacts slowly with water but very rapidly with oxygen on the voltammetric time scale.

Systematic approach to the quantitative voltammetric analysis of the Fe(super III)/Fe(super II) component of the [alpha(sub 2)-Fe(OH(sub 2))P(sub 2)W(sub 17)O(sub 61)](super 7-/8-) reduction process in buffered and unbuffered aqueous media

Article Abstract:

The one-electron reduction of [alpha(sub 2)-Fe(OH(sub 2))P(sub 2)W(sub 17)O(sub 61)](super 7-) at a glassy carbon electrode was investigated using cyclic and rotating-disk-electrode voltammetry in buffered and unbuffered aqueous solutions over the pH range 3.45-7.50 with an ionic strength of approximately 0.6 M maintained. Analysis of the simulations illustrates the contribution of the buffer in terms of general acid-base catalysis, a pathway not available in unbuffered media.

Voltammetric studies with adhered microparticles and the detection of a dependence of organometallic Cis(super +)-trans(super +) first-order isomerization rate constants on the identity of the ionic liquid

Article Abstract:

The voltammetric measurements with organometallic microparticles, adhered to an electrode in contact with ionic liquids, facilitate the quantitative measurements of first-order homogeneous process coupled to the electron-transfer process. The rate constants for the isomerization processes that are obtained in four hydrophobic ionic liquids have widely varying physical and chemical properties.
