Interaction of sodium and calcium ions with poly(alkylene phosphate)—a synthetic analogue of natural teichoic acids
Literature Information
The competitive binding of sodium and calcium ions to poly(alkylene phosphate)s, which can be considered as synthetic models of bacterial teichoic acids, and to poly(styrenesulfonate)s was studied experimentally by potentiometry with ion-selective electrodes. The fractions of apparently free counterions, ffi, were determined and compared with theoretical predictions obtained from the Poisson–Boltzmann theory applied to the cylindrical cell model of polyelectrolyte solutions containing a mixture of counterions differing in charge. For the studied systems, the dependence of ffNa and ffCa on the composition of the counterion mixture and on a charge density parameter of the polyion was found to be fairly well described by theory. For poly(alkylene phosphate)s the calculated values of ffi noticeably exceeded the measured fractions of apparently free ions. Much better agreement between theory and experiment was obtained if the effective value of the charge density parameter was used.

Physical Chemistry Chemical Physics

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
