摘　　要：饮用水是人体铝元素的主要摄入来源.微量铝离子可对人体健康造成很大危害.WHO(世界卫生组织)规定,饮用水中允许的最高铝离子浓度为200μg/L(7.41μmol/L).因此铝离子的高灵敏检测显得尤为重要.目前常用的铝离子检测方法存在操作麻烦,周期长等缺点,所以构建一种简便、快捷的铝离子检测方法尤为重要.丹皮酚是一种提取自牡丹皮的有机化合物,其与Al^(3+)结合后荧光会数倍增强.基于丹皮酚与铝离子结合产生荧光增强现象,建立了一种检测铝离子的荧光分析方法.此方法只需常温反应5 min,并且检测限为0.5μmol/L(线性范围:0~100μmol/L),构建的检测方法具有快速、低成本、简单、高特异性和高灵敏等优点,有很好的应用前景.Drinking water is a major source of aluminum intake for humans.Trace amounts of aluminum ions can cause significant harm to human health.The World Health Organization(WHO)sets the maximum allowable concentration of aluminum ions in drinking water at 200μg/L(7.41μmol/L).Therefore,high-sensitivity detection of aluminum ions is crucial.Current aluminum ion detection methods often suffer from complex procedures and long processing times.Consequently,developing a simple and rapid method for aluminum ion detection is important.Paeonol,an organic compound extracted from peony bark,exhibits a significant fluorescence enhancement when it binds with Al^(3+).Based on this fluorescence-enhancing property,a fluorescence method was established to detect aluminum ions.This method requires only 5 minutes of reaction time at room temperature,with a detection limit of 0.5μmol/L(linear range:0~100μmol/L).The developed method is fast,low-cost,simple,highly specific,and sensitive,offering great application potential.
