【摘要】 本文成功构建了具有Fe³⁺荧光体系的萘酰亚胺荧光探针M1,并对其紫外可见吸收光谱和荧光发射光谱进行了研究。在最优实验条件下,系统具有良好的抗干扰能力。M1探针与Fe³⁺浓度呈良好的线性关系(1×10^-6～15×10^-6 mol·L^-1)。检出限为7.55×10^-8 mol·L^-1。M1探针与Fe³⁺的络合比为1:1。我们首次利用构建的M1探针结合Fe³⁺荧光系统测定了中药西洋参和白芍中Fe³⁺的浓度。更多还原

【Abstract】 In this paper,the naphthylimide fluorescent probe M1 with Fe³⁺ fluorescence system was successfully constructed and its UV-vis absorption and fluorescence emission spectra were investigated.Under the optimal experimental conditions,the system showed good immunity to interference.The M1 probe showed a good linear relationship with Fe³⁺concentration(1×10^-6～15×10^-6 mol-L^-1).The detection limit was 7.55 × 10^-8mol.L^-1.The complexation ratio of M1 probe to Fe³⁺ was 1:1.We determined the concentration of Fe³⁺ in the traditional Chinese medicines American ginseng and Paeonia lactiflora for the first time by using the constructed M1 probe-conjugated Fe³⁺ fluorescence system.更多还原
