Experimental Setup in Electrokinetic Measurements

Electrokinetic phenomena are irreversible processes, in which an electric force induces a coupled mechanical flux or a mechanical force induces a coupled electric flux, in the direction tangential to a charged surface. The potential is calculated from the phenomenological coefficients in the relationships between the force and the coupled flux in these phenomena. [Pg.41]

The pHo obtained by means of electrokinetic measurements is reported as iep in the Method columns in the tables in Chapter 3. The trade names of commercial instruments or short descriptions of home-made instruments used for electrokinetic measurements are given when possible. The present approach is different from that in [2], in which the type of instrument was not specified. Moreover, the present book does not consider pHg values obtained by means of an electroacoustic method as a separate category, and they are also reported as iep. [Pg.41]
