Molecularly Imprinted Polymers (MIPs) are the group of polymers that possess an ability to selective recognize analytes or groups of analytes, which are similar by their structural construction. The recognizing ability, which is generated during the synthesis of material, is determined by various factors such as shape, size, and the presence of functional groups in the MIP cavity. This molecular recess is created as a result of removing the specific analyte from the inclusive complex (polymeranalyte). Thanks to the valuable properties of molecularly imprinted polymers, these materials are commonly used in various fields. The multitude of their applications results from their properties such as high physical stability to harsh chemical and physical conditions, straightforward preparation, remarkable robustness, excellent reusability, and relative low-cost synthesis. Due to the attractiveness of MIPs widely demonstrated in the literature, as well as the possibilities of their application in various fields, these materials also have gained the favor of Professor Grzegorz Schroeder’s research group, in which numerous scientific works devoted to the subject of their use have been published.

Functional polymers are increasingly being used as materials with a range of unique properties. Due to their structure and relatively high flexibility in a synthetic context, they are becoming highly relevant in a variety of applications. One of the numerous examples of the use of functional polymers is water treatment. Using the adsorption phenomenon, it is possible to remove or reduce the amount of harmful organic compounds and heavy metal ions in the water. This review provides information on both the synthesis methods and characterization of functional polymers in terms of their adsorption properties. Among others, this paper presents the results of research on functional polymers carried out by Professor Schroeder's research group. The research was mainly focused on the selective adsorption of dyes and heavy metal ions, which are significant water pollutants. The overall results show that the adsorption of the synthesized polymer materials is high influenced by parameters such as pH, temperature, contact time of the adsorbent with the adsorbate and the initial adsorbate concentration. In the case of the adsorption phenomenon, the Langmuir or Freundlich isotherm turned out to be the most appropriate model for the tested materials, while in the case of kinetic models, the highest R2 coefficient was usually obtained using the pseudo-second-order equation.
