Abstract :A new calix[4]arene derivative, 3, which functionalized at the lower rim with 2-insert ignore into journalissuearticles values(2-aminoethyl amino);-5-nitropyridine, was synthesized and characterized by a combination of FTIR, 1H NMR, 13C NMR, and elemental analysis. Then the calix[4]arene 3 was grafted onto [3-insert ignore into journalissuearticles values(2,3-epoxypropoxy);propyl]trimethoxysilane-modified Fe3O4-- nanoparticles insert ignore into journalissuearticles values(EPPTMS-MN); to produce new calixarene-adorned magnetic nanoparticles insert ignore into journalissuearticles values(MN-DiNoPy-Calix insert ignore into journalissuearticles values(4););. The structure of the calixarene-adorned magnetic nanoparticles 4 was determined by a combination of FTIR, TEM, and elemental analysis. Moreover, a study regarding the removal of toxic HCr2O7- anion from aqueous solution was also carried out with the calixarene-adorned magnetic nanoparticles in solid--liquid extraction studies.
