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.

Glycidyl methacrylate copolymers modified with diamines as effective nucleophilic scavengers

Bukowski W., Bukowska E.

Polish Journal of Chemical Technology

2006

Vol. 8, nr 3

73-75

Three-components glycidyl methacrylate terpolymers were chemically modified in the reaction with ethylenediamine or trans-1,2-diaminocyclohexane. The reactive resins which contain 1.6 - 2.0 mol N/g were obtained as a result. The latter resins were tested as rapid scavengers of salicylaldehydes, benzoil chloride and 4,4'-diphenylmetane diisocyanate.
