文摘

Sorbents containing quinolin-8-ol groups were synthesized by the chemical transformation of macroporous poly(glycidyl methacrylate-co-ethylene dimethacrylate) copolymer using the Mannich reaction. These sorbents were transformed into Ag(I), Cu(II), and Fe(III) forms, respectively. The interactions with substituted phenols were studied by inverse liquid chromatography. Phenols are retained more strongly on the metal complexes of quinolin-8-ol sorbent than on the uncomplexed quinolin-8-ol sorbent. Strong interactions of benzene-1,2-diols, benzene-1,2,3-triols and 4-nitrophenol with the adsorbent in the Cu(II) and Fe(III) form are explained by the chelate effect or by ionic bond formation. The intensity of the interactions decreases when the eluents are exchanged from water or water/methanol mixtures to the less polar methanol.
