标准范围

本文件规定了在多孔材料中测定ζ电位的方法，所述多孔材料被液体饱和，其中孔是容易接近的。对ζ电位的值或多孔材料的孔隙率没有限制。假设孔在数百微米或更小的尺度上，对孔几何形状没有任何限制。本文件涵盖了使用水性介质作为润湿液体的交流(AC)和直流(DC)方法的应用。本文仅限于线性电动效应。

This document specifies methods for the zeta potential determination in porous materials that are saturated with a liquid where the pores are readily accessible. There is no restriction on the value of the zeta potential or on the porosity of the porous material. A pore is assumed to be on the scale of hundreds of micrometres or smaller without any restriction on pore geometry.

This document covers the applications of alternating current (AC) and direct current (DC) methods using aqueous media as wetting liquids.

This document is restricted to linear electrokinetic effects.
