It was introduced by Lyklema in “Fundamentals of Interface and Colloid Science”.〔Lyklema, J. “Fundamentals of Interface and Colloid Science”, vol.2, page.3.208, 1995〕 IUPAC Technical Report prepared by a group of most known world experts on this subject uses this term explicitly. Dukhin number is a ratio of the surface conductivity $\backslash kappa^$ to the fluid bulk electrical conductivity Km multiplied by particle size a : :$\backslash \; Du\; =\; \backslash fraca\}$ There is another expression of this number that is valid when surface conductivity is associated only with ions motion above slipping plane in the double layer. In this case, value of the surface conductivity depends on ζ-potential, which leads to the following expression for the Dukhin number for symmetrical electrolyte with equal ions diffusion coefficient: :$\backslash \; Du\; =\; \backslash fraca\}\backslash left(\backslash mathrm\backslash frac-1\backslash right)$ where parameter ''m'' characterizes contribution of electro-osmosis into motion of ions within DL: :$m\; =\; \backslash frac$ * F is Faraday constant * T is absolute temperature * R is gas constant * C is ions concentration in bulk * z is ion valency * ζ is electrokinetic potential * ε0 is vacuum dielectric permittivity * εm is fluid dielectric permittivity * η is dynamic viscosity * D is diffusion coefficient There are several ways to measure Dukhin number.〔 ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Dukhin number」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
