Abstract

144,710. Elektro-Osmose Akt.-Ges. (Graf Schwerin Ges.). April 8, 1918, [Convention date]. Electric endosmose.-Before the separation by electric endosmose of mixtures of colloids, ions, and non-ionized bodies, ions which are unsuitable for the process are replaced by more suitable ones, for instance chloride, sulphate, or phosphate ions by inorganic or organic ions of the samel or different valency, or calcium, magnesium, or aluminium by ammonium, sodium, or potassium. If a mixture containing ammonium sulphate and albumen is treated in a three-compartment cell, even the most electro-positive diaphragms do not prevent more rapid migration of the ammonium ions and consequent acidity of the mixture in the middle compartment; but after treatment of the mixture with barium acetate and removal of barium sulphate, the mixture on electrolysis with a positive diaphragm at the anode remains feebly alkaline and albumen is not precipitated. If barium chloride is similarly used, the mixture keeps feebly acid. Both anions and kations can be replaced; for instance, if aluminium sulphate is present, the aluminium can be replaced by ammonium and the sulphate ion by a monovalent one.
