Influence of the Structure of Sulfonic Polyelectrolyte Matrices on the Adsorption of Cu2+ Ions
Porous hydrophilic polyelectrolyte matrices have been obtained by reverse suspension copolymerization of p-styrenesulfonate with N,N'-methylenebisacrylamide, as well as by cryotropic gelation of sulfonic acrylates (3-sulfopropyl methacrylate and sulfobetaine methacrylate). It has been shown that the concentration of sulfonate groups in the obtained polyelectrolytes is 2–3 mmol/g. The morphology and structure of the surface layer of the polyelectrolyte matrices have been studied by scanning electron microscopy and FTIR spectroscopy, while the specific surface area and pore size distribution have been investigated by the BET method. Adsorption of Cu2+ ions has been studied spectrophotometrically. It has been found that polyelectrolyte matrices containing aromatic sulfonate groups have the maximum sorption capacity.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
