Resumo |
Based on rhodamine 6G, a highly sensitive and selective fluorescent sensor R6G1 for Hg2+ detection had been designed and prepared. It was synthesized through the well-known reaction that thiourea derivatives with amine could easily be transformed into guanidine derivatives with the promotion of Hg2+. By coordination with Hg2+, R6G1 exhibited high sensitivity and selectivity over other metal ions in aqueous systems. Furthermore, fluorescence titration experiments established the well-fitted linearity function of the fluorescent intensity with the concentration of Hg2+ in aqueous solution. The results showed that R6G1 provided high water solubility and high selectivity toward Hg2+ but no significant response toward other competitive cations and anions. It was suggested that the chemosensor would find its application in environmental field requiring rapid and accurate Hg2+ ion analysis. |
