EFFECT OF ALKALI-METAL CHLORIDES ON THE DISTRIBUTION OF SERUM-ALBUMININ THE WATER INTERFACIAL ADSORPTION LAYER TOLUENE SYSTEM - 2 - EFFECTOF SALTS ON THE EQUILIBRIUM DISTRIBUTION OF PROTEIN IN THE SYSTEM

The adsorption isotherms of bovine serum albumin (BSA) in the interfac ial layer and isotherms of its equilibrium concentration in the hydroc arbon phase are given for a wide range of the BSA concentrations in th e aqueous phase in the presence of electrolytes. Separate parts of the isotherms are analytically described. The coefficients of protein dis tribution between the interfacial layer and two macrophases (aqueous a nd hydrocarbon) in the presence of salts were calculated. At high BSA concentrations, a polycomponent polymolecular interfacial layer is for med-the third intermediate phase. In the presence of the alkali metal chlorides, a third phase is formed at higher protein concentrations.
