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
硫化氢 (H 2 S) 是一种无色、有臭味的有毒物质,存在于水体和废水中,特别是在职业敏感环境中,浓度较高时会对人体产生有害影响。合成了 H 2 S 监测探针 NNAP,其显示 pH 依赖性电化学、比色和荧光响应。 NNAP 在 pH 7.4 下充当荧光传感器,检测限 (LOD) 为 0.70 mM;在 pH 12 下充当比色传感器,肉眼可辨别可见的颜色变化,LOD 为 4.28 mM。此外,它还展示了在 pH 2 时电化学传感的实用性,LOD 为 2.5 mM。此外,NNAP 涂层纸条已成功用于实时 H 2 S 监测应用。 图解摘要
