Here, we report the catalytic activity of catalyst derived from polyethylene imine-M (II) (PEI-M: Cu(II), and Co(II)) hydrogel composite in the presence of H2Oas an oxidant. The PEI-Cu(II)/H2O2 heterogeneous composite was used in the degradation of an azo-dye, methyl orange (MO) in aqueous solution. In the presence of 63 mM H2O2, 100% of MO was removed in 80 min. The kinetics investigation of the processes demonstrated a pseudo-first-order kinetic model was applicable. Additionally, a pharmaceutical product, epinephrine (EP) was partially oxidized to adrenochrome by PEI-Co(II)/H2O2 hydrogel composite system. About 50% of conversion to adrenochrome was reached in less than 55 min again comply with the pseudo-first-order kinetic model. Both MO and EP oxidation reaction provided mild activation energies, 44.09, and 58.02 kj.mol-1, respectively. Various parameters effecting MO and EP oxidation were investigated.

Bu çalışmada, Polietilenimin-M(II) (PEI-M: Cu(II) ve Co(II)) hidrojel kompozitlerinin H2O2 indirgeyici olarak kullanılıdığı reaksiyonlarda katalitik aktiviteleri incelendi. Buna göre, PEI-Cu/H2O2 heterojen kompozitleri metil oranjın sulu çözeltisinde (MO) bozunma reaksiyonunda katalizör olarak kullanıldı. Metil oranj, 63 mM H2O2 varlı- ğında %100 olarak 80 dakikada ortamdan uzaklaştırıldı. Metil oranj bozunma reaksiyonunun kinetik çalışmalarında pseudo birinci dereceden kinetik modele uygulanabilir olduğu gösterildi. Bunlara ek olarak, bir ilaç olan epinefrin (adrenalin), PEI-Co(II)/H2O2 hidrojel kompozit sistemi varlığında adrenokrom'a yükseltgendi. Epinefrin'in yaklaşık %50'si 55 dakikadan daha az bir sürede adrenokroma dö- nüştürüldü ve pseudo birinci dereceden kinetik modele uygulanabilir olduğu gösterildi. MO ve EP yükseltgenmesi reaksiyonlarının aktivasyon enerjileri sırasıyla 44,09 ve 58,02 Çanakkale Onsekiz Mart Üniversitesi Fen Bilimleri Enstitüsü Dergisi 3 kj.mol-1 olarak hesaplandı. MO ve EP oksidasyonuna etki eden çeşitli parametreler çalışıldı.
