Tubular dialysis cell, for suspending in an electrophoretic dip coating bath, has a plastic membrane tube incorporating an anion exchange resin

摘要

A tubular dialysis cell comprises a plastic membrane tube incorporating an anion exchange resin. A tubular dialysis cell has a tubular membrane-forming housing, enclosing an anode rod or tube, and supply and return connections for anolyte circulation between the anode and the housing, the housing being formed by a porous plastic tube containing a homogeneously distributed anion exchange resin or by a double-walled plastic tube containing an anion exchange resin in the narrow annular gap between its walls.
