Abstract

Hydrogen sulfide (H2S) is a colorless, foul smelling, toxic substance that can be found in water bodies and waste waters, especially in occupational susceptible environments, and can lead to harmful effects in humans at higher concentrations. An H2S monitoring probe NNAP is synthesized, which displays pH-dependent electrochemical, colorimetric, and fluorescence responses. NNAP functions as a fluorometric sensor at pH 7.4, with a limit of detection (LOD) of 0.70 mM, and as a colorimetric sensor at pH 12, where visible color changes are discernible to the naked eye, with an LOD of 4.28 mM. Additionally, it demonstrates utility in electrochemical sensing at pH 2, with a LOD of 2.5 mM. Furthermore, NNAP-coated paper strips have been successfully utilized for real-time H2S monitoring applications.

Abstract Image

用于监测水中 H2S 的多功能 pH 值荧光、比色和电化学传感器。
硫化氢(H2S)是一种无色、恶臭的有毒物质,可在水体和废水中发现,尤其是在易受职业影响的环境中,浓度较高时会对人体产生有害影响。我们合成了一种 H2S 监测探针 NNAP,它能显示出与 pH 值相关的电化学、比色和荧光反应。在 pH 值为 7.4 时,NNAP 可用作荧光传感器,检测限(LOD)为 0.70 毫摩尔;在 pH 值为 12 时,NNAP 可用作比色传感器,肉眼可观察到明显的颜色变化,检测限为 4.28 毫摩尔。此外,它还可用于 pH 值为 2 的电化学传感,最低检测限为 2.5 毫摩尔。此外,NNAP 涂层纸条已成功用于实时 H2S 监测应用。

期刊介绍: Journal of Fluorescence is an international forum for the publication of peer-reviewed original articles that advance the practice of this established spectroscopic technique. Topics covered include advances in theory/and or data analysis, studies of the photophysics of aromatic molecules, solvent, and environmental effects, development of stationary or time-resolved measurements, advances in fluorescence microscopy, imaging, photobleaching/recovery measurements, and/or phosphorescence for studies of cell biology, chemical biology and the advanced uses of fluorescence in flow cytometry/analysis, immunology, high throughput screening/drug discovery, DNA sequencing/arrays, genomics and proteomics. Typical applications might include studies of macromolecular dynamics and conformation, intracellular chemistry, and gene expression. The journal also publishes papers that describe the synthesis and characterization of new fluorophores, particularly those displaying unique sensitivities and/or optical properties. In addition to original articles, the Journal also publishes reviews, rapid communications, short communications, letters to the editor, topical news articles, and technical and design notes.
