This study
reports the preparation and characterization of a new polymeric fluorescence
sensor for the determination of boron. The sensor was prepared by the UV-curing
of Glucosyloxyethyl methacrylate (GOEM), 1,6-Hexandiol diacrylate (HDDA), hydroxyethylmethacrylate (HEMA) and 2,2’-dimethoxy-2-phenylacetophenone
(DMPA) was used as the photoinitiator. The features of the sensor performance
including sensitivity, response time, pH effect, stability and matrix
interferences were studied. The excitation and
emission wavelengths of the fluorescence sensor were 378 and 423 nm,
respectively. With the prepared fluorescence sensor, the optimum pH value for
the boron solution was determined as pH 6.0, and the optimum analysis time was
selected as 45 seconds. The linear response range under the optimized
conditions was found to be 9.25 × 10-7 mol L-1 and 9.25 ×
10-6 mol L-1. The limit of detection (LOD) was
2.90 × 10−8 mol L-1 and the limit of
quantification (LOQ) was 9.66 10−8 mol L-1 (n=7)
with 1.2% relative standard deviation. In addition,
boron could be selectively detected by the prepared polymeric sensor even in
the presence of foreign ions. The prepared sensor was also
successfully applied to real environmental water samples.
