Abstract :T his 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 insert ignore into journalissuearticles values(GOEM);, 1,6-Hexandiol diacrylate insert ignore into journalissuearticles values(HDDA);, hydroxyethylmethacrylate insert ignore into journalissuearticles values(HEMA); and 2,2’-dimethoxy-2-phenylacetophenone insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(LOD); was 2.90 × 10 −8  mol L -1 and the limit of quantification insert ignore into journalissuearticles values(LOQ); was 9.66 10 −8  mol L -1 insert ignore into journalissuearticles values(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.
