The aim of the research was to use a novel group of sorbents with a silica and polymer matrix in the process of removing metal ions, which in their structure contain permanently deposited groups capable of coordinating various types of metal ions. The implementation of individual stages of the research allowed for the development of methods for the synthesis of materials characterized by an ordered spatial structure, incorporation in the polymer matrix and silica network of pyridinium groups ensuring above-average sorption properties and determining the parameters determining the potential of the obtained materials as metal ion sorbents from waste solutions.
