| Abstract | : | A simple and sensitive colorimetric sensor for nickel(II) ions has been successfully prepared by immobilizing α-furil dioxime reagent in the sol-gel matrix with a solid supporting filter paper medium. The sensor was developed using tetraethyl orthosilicate (TEOS) precursors with 4 days aging time, the mole ratio of water: precursor 4:1, and reagent concentration 0.10 %. The sensor was quantified by utilizing the Red (R), Green (G), and Blue (B) values of the colors that were successfully displayed after the detection process. The RGB value is confirmed by the Euclidean Distance (ED) equation to determine the optimum conditions. There was no observed degree of leaching in plain sight, and the result of leaching investigation by the double dyeing method did not show significant change either. The linear range was 0.10 to 2.8 ppm with an R2 of 0.9964. The process LOD and LOQ were 0.119 ppm and 0.397 ppm, respectively. In addition, the sensor was free from interfering species and had a percent recovery between 80 and 110%. |
