THE SYNTHESIS OF SPHERICAL SHAPE AMINO FUNCTIONALIZED PEI-TGIC COVALENT ORGANIC FRAMEWORKS: SYNTHESIS, CHARACTERIZATION, AND METHYL ORANGE ABSORPTION

Abstract

In here, the synthesis of covalent organic framework (COF) from the reaction of polyethyleneimine (PEI) and triglycidyl isocyanurate (TGIC) in dimethylformamide at 90 oC were carried out. The surface are, pore volume and pore size values of PEI-TGIC COFs observed as 23.4 m2/g, 0.143 cm3/g, and 22.5 nm, respectively. Moreover, the surface charge of PEI-TGIC COFs increased to +46.1±2.6 mV from +18.3±1.7 mV, after protonation of amine groups of PEI-TGIC COFs. Moreover, the potential usage of PEI-TGIC based COFs in absorption methyl orange (MO) dye from aqueous media was testing. It was observed that, the PEI-TGIC COF absorbed 156.6±4.9 mg/g MO, and the protonated PEI-TGIC (p-PEI-TGIC) COFs absorbed 202.4±5.3 mg/g MO from aqueous media in 30 min. The MO absorption by PEI-TGIC COF fitted with pseudo-first-order kinetic model, whereas MO absorption by p-PEI-TGIC COF fitted with pseudo-second-order kinetic model.
