| Abstract: | A new
glycylcalix[6]arene is synthesized by the reaction of glycine ethyl ester
hydrochloride with acid chloride of p-carboxycalix[6]arene.
Its physical properties, void volume, density, swelling, cation exchange
capacity and t1/2 have been determined. The glycylcalix[6]arene is
used as resin and its metal ion exchange capacities are determined. Mn(II),
Fe(II), Co(II), Cu(II), Ni(II) and Zn(II) were absorbed at 5.5, 4.5, 6.0, 4.0,
4.8 and 5.0 pH, respectively. These were eluted with NaF, H2SO4,
acetic acid, tartrate and HCl. The chromatographic separation of
Mn(II), Fe(II) Co(II), Ni(II), Cu(II) and Zn(II) from each other was studied.
These metals were preconcentrated on resin and determined in blood plasma and
in the environment samples. |
