Influence of Solution pH on the Nanostructure of Adsorption Layer of Selected Ionic Polyamino Acids and Their Copolymers at the Solid-Liquid Interface

摘要

32.1 Introduction Adsorption of polymer macromolecules at the solid-liquid interface is a very sophisticated process [1-3]. The polymer chains' arrangement depends on various factors which can be derived into three main groups. The first one includes the parameters associated with the adsorbent such as surface active group quantity, presence of net impurities, and pore size characteristics. The next group contains the factors directly related to the adsorbed species, mainly the adsorbate molecule structure. The last class refers to the adsorption process parameters. Thus, one can distinguish the temperature, solution strength, background electrolyte type, pH changes, and presence of additional substances (e.g., surfactants) [4-10].
