摘 要: 研究了过渡金属离子对荧光分子 1 萘胺二乙酸钠 (NADA)的荧光猝灭现象及其猝灭机理 ,并基于此建立铜离子传感体系。该铜离子传感器的检测限为8.2 7× 1 0 - 6mol/L ,定量检测范围为 2 .6 9× 1 0 - 5~ 1 .2 0× 1 0 - 4 mol/L。 The fluorescence character of sodium 1-naphthylaminodiacetate quenched by metal ions was reported, and the fluorescence quenching mechanism was discussed. The method was used to determination of Cu(Ⅱ) with detection limit of 8.27×10 -6 mol/L. A linear relationship was observed over 2.69×10 -5~1.20×10 -4 mol/L.
