Bis (Salysylaldehyde) Benzidine for the Highly Selective Cu2+-Sensing by Fluorescence Quenching


Objectives: Preparation of an aromatic compound with high Fluorescence spectral properties that can be used as a sensor for metals in the water medium. Methods/Statistical Analysis: A new Fluorescent Sensor Bis (salysylaldehyde) Benzidine was produced by the interaction of benzidin with (salysylaldehyde).The designing and synthesizers of compunds to eclectic and detection of biological and environmental significant ionic types have involved extensive attention. Findings: Bis (salysylaldehyde) Benzidine an active fluorescent sensor for (Cu2+) in water solution was considered and produced. A color change was simply observing when mixing of Cu2+, also fluorescence quenching was identified. The fluorescent quenching of Bis (salysylaldehyde) Benzidine-Cu2+complicationpresented the limit of detection was 1.96. Application/ Improvements: Bis (salysylaldehyde) Benzidine can performance as a high Selective for Cu2+ and can be utilized to quantitatively detect low levels of Cu2+ in water solution. In arrangement the test indicates high selectivity and affectability toward Cu2+ion over other metal ions.
