In this study, macroporous poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate) was synthesized by suspension copolymerization, functionalized by ring-opening reaction of the pendant epoxy groups with diethylene triamine and used for immobilization of Pd(II) ions from chloride and nitrate solutions under batch experimental condition. The amino-functionalized sample and samples with immobilized Pd(II) ions were characterized by Fourier transform infrared spectroscopy (FTIR) analysis and scanning energy-dispersive X-ray spectroscopy (SEM-EDX). The electrochemical behavior of electrodes composed of synthesized samples was tested in 0.1 M H2SO4 by means of cyclic voltammetry (CV). The shape of recorded CV showed dependence on the type of Pd-salt used for Pd immobilization. The reaction of oxidation of 4-chlorophenol (4-CP) from 0.1 M H2SO4 at investigated samples was also studied. Electrooxidation of 4-CP resulted in passivation and formation of reversible hydroquinone/benzoquinon...e on both investigated electrodes, although hydroquinone/benzoquinone formation was more pronounced on Pd immobilized from nitrite solution.
