PY - 2019 T2 - Applied Physical Pharmacy, 3e AB - Learning ObjectivesAfter completing this chapter, the reader should be able to:Discuss the significance of surface and interfacial phenomena in biological and pharmaceutical systems.Measure surface and interfacial tensions of liquids using the appropriate method.Estimate the ability of a liquid to spread over a surface.Propose ways to enhance the wettability of pharmaceutical powders in liquid media.Organize surfactants in different categories.Classify surfactants on the basis of their hydrophile–lipophile balance values.Evaluate the process of adsorption at the liquid–air interface, with emphasis on the adsorption of surface active agents (surfactants).Determine the critical micelle concentration of a surfactant.Calculate the surface excess concentrations and molecular areas of adsorbing species by using the Gibbs adsorption equation.Discuss the adsorption of gases on solid surfaces and the use of the Langmuir, Freundlich, and BET adsorption isotherms.Analyze adsorption isotherm data and calculate the amount of adsorbate required to form a monolayer, and the specific surface area of the adsorbent.Assess the adsorption at the solid–liquid interface, and discuss the adsorption of proteins onto solid surfaces.
