NMR Spectroscopic Study of Phosphorus-Containing Polymer Sorbent

摘要

The nature and distribution of functional groups in the polymer matrix, as well as the nature of the spatial network in the phosphorus-containing polymeric sorbent was studied by the method of NMR spectroscopy. The phosphorus-containing polymer sorbents are widely used for extraction, concentration, and separation of heavy and radioactive metals. Their main sorption properties, that is, capacity and selectivity, are defined by such characteristics as the nature of functional groups, their distribution and state of the phosphorus in the matrix, which depend on the selection of initial components, their ratio, the method and conditions of their synthesis.
