Chemoelectronic mobilization of chemical species in low-conductivity fluids: new electrokinetic effect.

RESUMO

An electrokinetic phenomenon is reported here which differs from its classical counterparts most distinctively by nonlinear conductivity and mobility. Neither purely electrolytic nor electrostatic in nature, this phenomenon is presumed to involve subtle charge transfer effects and association reactions permitting a controlled "chemoelectric" mobilization. In its electrokinetic manifestation, this phenomenon can be used to mobilize chemical species commonly with migration rates orders of magnitude greater than can be achieved electrophoretically and is shown to induce the movement of nonpolar molecules, such as aromatic hydrocarbons, at rates exceeding several centimeters per minute in easily achievable voltage gradients. The operational technique, developed as a separations method used for demonstrating the effect, is called "electromolecular propulsion".
