联苯类比率型荧光探针检测水中硫化氢
Determination of Hydrogen Sulfide in Water by Biphenyl Ratio Fluorescence Probe
摘要
Abstract
A biphenyl-derived ratiometric fluorescent probe(WN) for the detection of H2S was synthesized using 4,4′-biphenyl dicarboxylic acid as the raw material and characterized by 1H NMR, 13C NMR, and MS.For the purpose of detection of H2S in aqueous solution, its fluorescent properties had been systematically researched.The results show that probe WN exhibits good sensitivity and selectivity for detection of H2S, response time is 12 min.WN has strong anti-interference ability to biological mercaptan(Cys, Gsh), active oxides(H2O2, ClO-), various anions and cations(H2PO-4, SO2-4, Cl-, HCO-3, CO2-3, Mg2+, Zn2+, K+, Ca2+, Na+), and a good fluorescence response in a wide pH range, the fluorescence in tensity has good linear relation ships with H2S in the range of 1.1~350 μmol/L(R2=0.9943), the detection limit of H2S is estimated to be 1.07×10-6 mol/L.The test for three different water samples shows that the probe WN has a certain application significance in the detection of H2S in water.关键词
