	  abstract     = {An optical chemical sensing film based on
immobilizing of 1,1′- diethyl 2,2′-cyanine (pseudocyanine iodide) in
nafion film was developed for the determination of Fe(III). The
sensing film was homogeneous, transparent, and mechanically stable.
Decrease of the absorbance measured at 518 nm was observed when
the sensing film was immersed in a solution of Fe(III). The optimum
response of the sensing film to Fe(III) was obtained in a solution with
pH 4.0. Linear calibration curve over an Fe(III) concentration range
of 1-30 ppm with a limit of detection of 0.71 ppm was obtained.
Cd(II) is the major interference. The sensing film exhibited good
stability for 2 months and high reproducibility. The proposed method
was applied for the determination of Fe(III) in water samples with
satisfactory results.},
