THE ADSORPTION OF GELATIN BY COLLODION MEMBRANES [PDF]
An experimental study has been made of the adsorption of gelatin from solution at 37°C. by collodion membranes. In the case of membranes of high permeability, very high concentrations of gelatin were required to produce maximum adsorption, and the maximum amounts adsorbed were independent of the pH values of the solutions over the range 3.8 to 4.8 ...

PROTEIN FILMS ON COLLODION MEMBRANES [PDF]
1. Collodion membranes of high permeability were found to adsorb weighable amounts of gelatin and egg albumin from solution at 37°C. 2. The effect of protein concentration could be expressed fairly well by a hyperbolic equation proposed by Langmuir for the adsorption of gases by a plane surface, while the usual parabolic adsorption ...

ULTRAFILTRATION THROUGH COLLODION MEMBRANES [PDF]
It is obvious that the factors considered in this paper render data obtained by ultrafiltration open to criticism unless they are checked by other methods and precautions are taken for the elimination of the vitiating effects which have been described.

THE PERMEABILITY OF DRY COLLODION MEMBRANES. II [PDF]
The rate of penetration and the solubility of H, O, N, NH3, H2O, HCl gas, CO2, formic, acetic, chloracetic, dichloracetic acid, glycerol, phenol and mercury bichloride in dry collodion membranes have been measured. The rate of penetration of H and CO2 is the same whether the membrane and gas are dry or whether the membrane is immersed in

Selective Filtration of Antibiotics Through Collodion Membranes [PDF]
Marked differences were noted among 14 antibiotics in their filterability through collodion (nitrated cellulose) membranes. The findings could not be attributed to differences in molecular weight or degree of serum protein binding, although the latter factor imposed an additional restraint on the passage of certain agents.

THE PERMEABILITY OF THIN DRY COLLODION MEMBRANES [PDF]
Dry thin collodion membranes have been prepared which are permeable to water, ammonia, weak acids of low molecular weight, HCl gas, O2, CO2, and H2S, but are impermeable to strong electrolytes and substances of high molecular weight. The permeability to gases does not depend on the density, so that the gases do not pass through pores in the membrane.

THE ADSORPTION OF EGG ALBUMIN ON COLLODION MEMBRANES [PDF]
An experimental study has been made of the adsorption of purified egg albumin, from aqueous solution, on collodion membranes. At protein concentrations of 4 to 7 per cent apparent saturation values were obtained which resembled closely the results obtained with gelatin, showing a maximum at pH 5.0 and lower values on either side of this region.

EXPERIMENTAL STUDY OF OSMOSIS THROUGH A COLLODION MEMBRANE [PDF]
Experiments were carried out on a collodion membrane in order to study the factors that determine direction and magnitude of net flow of water across a membrane permeable to the solvent and to some of the solutes present. The solutes used were all non-ionic. When only one solute was present and there was no difference of hydrostatic pressure across the
