Abstract

Residual adipic dihydrazide (ADH) in textiles may react with formaldehyde to form hydrazone, which is a source of the formaldehyde pollutant indoors. In this paper, a xanthylium-based ratiometric fluorescent probe SH-Py was developed for ADH detection. The emission of SH-Py at 680 nm decreased, whereas that at 463 nm increased upon the addition of ADH in pure DMSO. The LOD was as low as 24.5 nM, and the possible sensing mechanism is presented. Good recoveries were observed in the standard recovery experiments of SH-Py for ADH detection in textiles. Moreover, the visualization of ADH in textiles was successfully achieved by spraying the probe solution and then inspecting it under a UV lamp. Additionally, SH-Py has the potential to quantify other aliphatic hydrazides in various samples.

使用基于黄原酸盐的比率荧光探针对纺织品中的己二酸二酰肼进行定量和目测。
纺织品中残留的己二酸二酰肼(ADH)可能会与甲醛反应生成腙,而腙是室内甲醛污染物的来源之一。本文开发了一种基于黄原鎓的比率荧光探针 SH-Py,用于检测 ADH。在纯二甲基亚砜中加入 ADH 后,SH-Py 在 680 nm 处的发射降低,而在 463 nm 处的发射升高。检测限低至 24.5 nM,并介绍了可能的传感机制。在纺织品中检测 ADH 的 SH-Py 标准回收实验中观察到了良好的回收率。此外,通过喷洒探针溶液,然后在紫外灯下检测,成功实现了纺织品中 ADH 的可视化。此外,SH-Py 还具有定量检测各种样品中其他脂肪族酰肼的潜力。
