Abstract :In here, the synthesis of covalent organic framework insert ignore into journalissuearticles values(COF); from the reaction of polyethyleneimine insert ignore into journalissuearticles values(PEI); and triglycidyl isocyanurate insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(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.
