摘要: 在蒽醌荧光团上修饰乙醇胺分子,合成了用于铁离子识别检测的新的荧光探针.实验结果表明,在乙醇:水=4:1,pH值为7.20的条件下,Fe3+的加入使体系荧光猝灭,荧光强度和Fe3+浓度在4.0×10-5-3.0×10-4 mol/L范围内呈线性关系,由此可以实现在乙醇/水体系中对Fe3+离子的高选择性检测.检测限为3.8×10-7mol/L.

Abstract: A new fluorionophore, which is composed of anthraquinone and a hydroxyl ethanol-amine receptor, has been synthesized. Effect of metal ions on the fluorescence of the ionophore was investigated. The results show that the ionophore displays a highly selective and sensitive response of fluorescence quenching toward Fe3+ in neutral buffer aqueous solution. There is a good linear relationship between the fluorescence intensity and Fe3+ concentration in the range of 4.0?10-5-3.0?10-4 mol/L. The detection limit is 3.8?10-7 mol/L.

Key words: anthraquinone, fluorescence, probe, iron ions, sensing
