Chronoamperometric mobilities in the electrodynamics of a non-aqueous sol: depletion, turbulence and electron transfer in sol electrodeposition

Abstract

The validity of a simple chronoamperometric technique for measuring the electrophoretic mobilities of colloid particles has been established by comparison of the results with those obtained from photon correlation spectroscopy, a well established method. Resolution of several flaws in the theory underlying chronoamperometric electrophoresis has led to a rationale of electrophoretic deposition based on turbulent liquid flow. The new theory also accounts for observations regarding the charge-transfer processes necessarily accompanying particle deposition.
