Hydrodynamic Radius of Poly (Ethylene Glycol) 8000 Determined from Aqueous Two-Phase System Containing High Concentration of Electrolyte

Adedayo A. Fodeke & Omolola M. Olajide · Asian Journal of Physical and Chemical Sciences · 2026

The hydrodynamic radius of poly(ethylene glycol) 8000 (PEG8K) was estimated using an aqueous two-phase equilibrium approach that requires no advanced analytical instrumentation. PEG8K solutions were prepared in phosphate buffer at pH 7.4 over an ionic-strength range of 1.2–2.0 mo...

Hydrodynamic Radius of Poly (Ethylene Glycol) 6000 Determined via Characterization of Composition-Dependent Aqueous Two-Phase Equilibrium System

Adedayo A. Fodeke · Asian Journal of Physical and Chemical Sciences · 2026

This work was carried out to develop a simple method for the determination of hydrodynamic radius of poly (ethylene glycol) 6000 (PEG-6000). The contribution of the activity coefficients of PEG-6000 and a mixture of phosphate and sodium chloride salts to the apparent equilibrium...
