In this study, Cd (II) ion
was determined using a cyclodextrin-based polymeric fluorescence sensor prepared
by UV-curing technique. The effects of several parameters such as pH, time, coexisting
ions on the fluorescence intensity were also examined. The excitation and
emission wavelengths were found to be 374 nm and 422 nm, respectively. The
measurement range was in the range of 4.45x10-9 mol L-1
to 4.45x10-8 mol L-1 for Cd(II) ions and the detection
limit was calculated as 6.23´10-10 mol L-1. In
addition, sensor membrane was selective which was not influenced by common coexisting
metal ions. The concentrations of the foreign ions such as Pb(II), Co(III),
Ag(I), Zn(II), Cu(II), Cr(III) are 1000-fold higher than Cd(II) ions. Besides
the prepared polymeric fluorescence sensor was successfully implemented to the
determination of Cd(II)ions in biscuit and tap water samples.
