Abstract :In this study, Cd insert ignore into journalissuearticles values(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 Cdinsert ignore into journalissuearticles values(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 Pbinsert ignore into journalissuearticles values(II);, Coinsert ignore into journalissuearticles values(III);, Aginsert ignore into journalissuearticles values(I);, Zninsert ignore into journalissuearticles values(II);, Cuinsert ignore into journalissuearticles values(II);, Crinsert ignore into journalissuearticles values(III); are 1000-fold higher than Cdinsert ignore into journalissuearticles values(II); ions. Besides the prepared polymeric fluorescence sensor was successfully implemented to the determination of Cdinsert ignore into journalissuearticles values(II);ions in biscuit and tap water samples.
