In the present work, a phenanthroline derivative (2-(2-methoxyphenyl)-4-phenyl-1,10-phenanthroline, MPP), as a fluorescent probe, was synthesized to realize a rapid, simple and sensitive detection of silver(I). The detection conditions of Ag⁺ were optimized. This fluorescent probe has the advantages of a fast reaction time, a wide pH applicable range, and a low detection limit, exhibiting a good linear response between the fluorescence intensity and the concentration in the range of 0.05 – 1.5 μmol/L for Ag⁺. The detection limit is as low as 3.38 × 10⁻⁸ mol/L (S/N = 3). This probe had been used to detect Ag⁺ in real samples, and the recovery efficiency of spiked Ag⁺ had been also tested. The recovery efficiency is satisfactory, ranging from 92.0 to 105.4%. Therefore, this fluorescent probe should provide a new choice for the quantitative detection of silver ions in environmental water samples.

在目前的工作中，合成了一种菲咯啉衍生物（2-（2-甲氧基苯基）-4-苯基-1,10-菲咯啉，MPP）作为荧光探针，实现了对银（I ）。优化了Ag ⁺的检测条件。该荧光探针具有反应时间快、pH适用范围广、检测限低等优点，在0.05-1.5μmol/L范围内对Ag ⁺的荧光强度与浓度之间表现出良好的线性响应。检测限低至 3.38 × 10 ^-8 mol/L ( S/N = 3)。该探针被用于检测的Ag ⁺实际样品中，并掺入Ag的回收效率⁺也经过了测试。回收效率令人满意，范围为 92.0 至 105.4%。因此，该荧光探针应该为环境水样中银离子的定量检测提供一种新的选择。
