As the iron content of wine affects the wine quality, a highly selective and simple detection method is needed to detect the iron content in wine. A colourimetric fluorescent probe (BTBAP probe) for the detection of total iron in wine was developed. The quantitative range of Fe content detected with the probe was 0 to 200 μM with a limit of detection (LOD) of 1.16 μM. After 10 min of Fe addition, the luminescence intensity of the BTBAP probe solution gradually decreased with increasing Fe concentration. Moreover, the B and G values of the luminescence photos were linearly related to the concentration of Fe (0-200 μM). BTBAP probe was successfully applied for rapid determination of the Fe concentration of wine. This work demonstrates that BTBAP probe is an excellent tool for rapid determination of the total iron content of wine using only a smartphone and no other professional equipment.
由于葡萄酒中的铁含量会影响葡萄酒的品质，因此需要一种高度选择性和简单的检测方法来检测葡萄酒中的铁含量。本文开发了一种用于检测葡萄酒中总铁的比色荧光探针（BTBAP 探针）。该探针检测铁含量的定量范围为 0 至 200 μM，检测限（LOD）为 1.16 μM。在加入铁 10 分钟后，BTBAP 探针溶液的荧光强度随铁浓度的增加逐渐降低。此外，荧光照片的 B 和 G 值与铁浓度（0-200 μM）呈线性关系。BTBAP 探针成功应用于快速测定葡萄酒中的铁浓度。这项工作表明，BTBAP 探针是一种使用智能手机和其他专业设备快速测定葡萄酒中总铁含量的优秀工具。
