Electrophoretic mass transport analyzer: operational characteristics with aqueous solutions and applicability to organic liquid-solid systems
Abstract
Operation of a Micromeritics Electrophoretic Mass Transport Analyzer (EMTA) is discussed, and preliminary results with both aqueous and organic systems are given. Use of the EMTA with aqueous mixtures has shown promising results. In particular, the behavior of kaolin-water and carbon-water systems is discussed, as well as carbon-benzene (an organic mixture). However, considerable difficulty was encountered with organic mixtures from the Solvent Refined Coal (SRC) process due to the very low conductivities of these systems. The Micromeritics EMTA could not measure conductivities in this range because of limitations on the resistance bridge in the measuring circuit. Additives, although successful in increasing conductivity, failed to provide a sufficient increase to bring the EMTA on scale. (DLC)
