Abstract :In this paper, synthesis of tetrakisinsert ignore into journalissuearticles values(carboxyphenyl);porphyrin insert ignore into journalissuearticles values(TCPP); coated cadmium ferrite insert ignore into journalissuearticles values(CdFe2O4); nanoparticles by using L-lysine as an anchor is reported for the first time. The ferrimagnetic CdFe2O4 nanoparticles were prepared via the facile self-assembly method of reflux followed by a heating treatment. The obtained magnetic nanoparticles were coated with TCPP in the presence of the amino acid L-lysine by sonication in ethanol and then refluxing for 12 h. The structural characteristics of the products were determined using FT-IR and XRD pattern. Scanning electron microscopy insert ignore into journalissuearticles values(SEM); images indicated uniform morphologies of the magnetic nanoparticles with an average size of 43 nm. The magnetic properties of the prepared samples were characterized on a vibrant sample magnetometer insert ignore into journalissuearticles values(VSM); with maximum saturation magnetization values of 65.09 and 46.80 emu/g for nanoparticles and nanoparticle/TCPP. The synthesized products were successfully employed to remove the methylene blue insert ignore into journalissuearticles values(MB); dye from aqueous solutions by using visible light irradiation. The magnetic CdFe2O4 nanoparticles indicated an enhancement of 13% for photodegradation of MB dye after being sensitized by TCPP.
