This study presents an innovative approach to measuring solvent activities in multicomponent mixtures using an improved isopiestic method. The objective is to refine and simplify the measurement techniques available for determining solvent activities, especially in aqueous polymer solutions. A novel apparatus was designed, allowing the simultaneous measurement of solvent activities for up to nine solutions, enhancing efficiency in experimental setups. Methodologically, the apparatus was employed to measure the solvent activities of six specific aqueous salt/polymer systems at a controlled temperature of 25°C. Results demonstrated the efficacy and accuracy of the improved method, which builds upon previously established isopiestic techniques, while addressing the complexity and cost limitations associated with traditional equipment. This advancement provides a more accessible tool for researchers investigating the thermodynamic properties of complex aqueous solutions, ultimately contributing to a deeper understanding of solvent behaviors in multicomponent systems.
