Two different approaches to XPS quantitative analysis of polyelectrolyte adsorption layers

Surface and Interface Analysis, Volume 55, Issue 1, Page 26-40, January 2023., 2023
X‐ray photoelectron spectroscopy (XPS) was employed to quantify adsorption of polyelectrolytes from aqueous solutions of low ionic strength onto mica, glass, and silica. Silica surfaces were conditioned in base or in acid media as last pre‐treatment step (silica‐base last or silica‐acid last, respectively). Consistency in the determined adsorbed amount,
