Open Access research with a real impact on health...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the Physical Activity for Health Group based within the School of Psychological Sciences & Health. Research here seeks to better understand how and why physical activity improves health, gain a better understanding of the amount, intensity, and type of physical activity needed for health benefits, and evaluate the effect of interventions to promote physical activity.

Abstract

Surface charging of polystyrene latex particles stabilized with sodium dodecyl sulfate (SDS) was investigated. The surfactant adsorption isotherm and electrophoretic mobilities of monodisperse latex particles were measured. Electrophoretic mobility measurements at moderate ionic strengths (around 0.1 M) indicated a substantial degree of counterion binding to adsorbed dodecyl sulfate anions, comparable to that found in SDS micelles. We offer a consistent description of surface charging of SDS-stabilized latex particles and SDS micelles taking into account binding of sodium counterions to dodecyl sulfate anions.
