Lz. Meng et al., Copolymeric network crown ether resins with pendent functional group: Synthesis and adsorption for metal ions, J APPL POLY, 76(9), 2000, pp. 1457-1465
Three network crown ether resins with a high content of pendent functional
groups were prepared and characterized by IR, elemental analysis, and therm
al analysis. The slight variance of the thermal stability of the resins was
related to the kind and content of the pendent functional group. The adsor
ption capacity of the resins for Mg(II), Cu(II), Co(II), Pb(II), and Hg(II)
was determined. Toward Hg(II), the adsorption capacity of the resins was h
igh and the adsorption process was easy and spontaneously performed. The XP
S study showed that the adsorption of the NCR-SN resin toward Cu(II), Pb(II
), and Hg(II) was mainly the coordinate interactions between the ligand ato
m (S, N) of the pendent functional groups and the metal ions. (C) 2000 John
