Modeling the Operation of a Microseparator Taking into Account the Changes in the Thickness of the Stern Layer on the Surfaces of Electrode Pores
Autor: N. A. Tikhonov, M. G. Tokmachev
Publikováno v: Russian Journal of Physical Chemistry A. 93:2528-2533
Mathematical modeling is used to study the deionization dynamics of an electrolyte solution via sorption on aerogel electrodes. The transfer of mass by the solution’s flow is considered, as are diffusion and sorption inside pores. It is shown that

Using Crosslinked Polyvinyl Alcohol Granules for the Determination of the Composition of Mixed Electrolyte Solutions
Autor: A. V. Ivanov, M. G. Tokmachev, I. I. Babayan, N. B. Ferapontov
Publikováno v: Journal of Analytical Chemistry. 74:834-838
A method is considered for determining concentrations of components in solutions of two electrolytes with one common ion. We used optical micrometry by measuring the degree of swelling of granules of crosslinked polyvinyl alcohol in a test solution.
