Abstract :

A solution chemistry study was conducted spectrophiotometrically to examine interaction between different cations and methyl-phenyl terpyridine compounds. A new versatile optical sensor based on silica for the highly sensitive and selective determination of mercury ion (Hg2+) based on a change in the absorption spectrum of a sol-gel film in an aqueous solution was proposed. A film was prepared composed of tetraethoxysilane (TEOS) and methyl-phenyl terpyridine (MPTPy) as chromoionophore and ethylene glychol (ETG) as surfactant additives. The influence of different parameters was studied for the sensitivity, linear range, and selectivity of the film. Satisfactory analytical sensing characteristics for determining Hg2+ ions were obtained in terms of selectivity, reversibility, and reproducibility with an excellent detecting range. In addition, the optical film responds to Hg2+ ion reversibly over a wide dynamic range of 1.0×10-8 to 1.0×10-3 mol/L with a response time of 5 Min. The proposed sol- gel film has been successfully applied to directly determine Hg2+ ion in spiked samples.
