The Structure of the Collodion Membrane and Its Electrical Behavior Ii, the Activated Collodion Membrane by Karl Sollner, Irving Abrams, and Charles W. Carr
In preceding communications t, 2 we were led to the conclusion that the electrochemical activity of collodion membranes, as manifested by concentration potentials, etc., is due principally to acidic impurities. Accordingly, different brands of collodion differ widely as to their activity, the purer brands being less active. The impure (but active) foreign brands of collodion, heretofore general...
متن کاملThe Structure of the Collodion Membrane and Its Electrical Behavior v. the Influence of the Thickness of Dried Collodion Membranes upon Their Electromotive Behavior by Karl Sollner and Charles W. Carr
The electrochemical properties of collodion membranes are known to vary greatly with the nature of the collodion preparation used, more acid preparations yielding membranes of higher electrochemical activity, x-s The assumption has always been made, tacitly or expressly, that the thickness of the membrane is of no influence. Thus, it has been generally assumed that the characteristic concentrat...
متن کاملStructure of T H E Collodion Membrane and Its Electrical Behavior Vi
Previous publications 1, ~ in this series have dealt with the preparation and electrochemical properties of the activated (electronegative) collodion membrane. The activation consisted of an oxidation of the nitrocellulose, a process which caused an increase in the number of dissociable groups in the pores of the membrane. Such membranes show more pronounced effects than similar untreated membr...
متن کاملTHE STRUCTURE OF THE COLLODION MEMBRANE AND ITS ELECTRICAL BEHAVIOR XI. Tm~ PREPARATION AND PROPERTIES OF "MEGAPERMSELECTIVE" COLLODION MEMBRANES COMBINING EXTREME Iomc SELECTIVITY WITH HIGH PERMEABILITY BY CHARLES W. CARR Am>
The classical investigations of Michaelis and collaborators 1 on the dried collodion membrane as well as the work of other investigators have revealed the basic physicochemical properties of membranes of porous character which are selectively cation-permeable. Dried collodion membranes prepared from suitable collodion ~-4 were found to allow the cations of uni-univalent strong inorganic electro...
