Abstract:
A fluorescence enhancement probe (ZY8) for the detection of N2H4was designed and synthesized by employing 3-hydroxyflavone as a fluorophore,and its spectral properties had been investigated. The results showed that ZY8 had relatively good selectivity and specificity to N2H4in Tris-HCl-ethanol solution (9:1, V/V, pH 7.40). The fluorescent intensity of ZY8 exhibited good linear relationship with concentration of N2H4in the concentration range of 1.6×10-7mol/L-6.2×10-5mol/L,and its detection limit was estimated to be 1. 6×10-7mol/L. ZY8 itself had weak fluorescence, upon addition of N2H4, an approximate 9-fold fluorescence enhancement was observed, and the color of the solution changed from light grayish green to bright grass-green at UV light of 365 nm. So ZY8 might be used to the visual recognition of N2H4. ZY8 could detect N2H4in near-physiological pH range, and it had fast response and strong anti-interference ability. Moreover,ZY8 could be loaded as test paper for naked-eye detection of N2H4at mmol/L level in water solution,and it was also applied in the determination of N2H4in various water samples by the standard addition recovery experiments, with the recovery ratio ranged from 96.0% to 104.2% %, and RSD of all< 4%. The results of this study demonstrated that ZY8 had potential application to the detection of N2H4in the monitoring of environmental pollution.
