| 中文摘要: |
| 设计合成了水溶性比色传感器磺酸功能化的偶氮水杨醛吖嗪（S），其结构经由1H NMR，ESI-MS确证。S在纯水与自来水中对氰离子（CN-）具有专一选择性的比色检测能力，最低检出限分别为0.16和0.63 μmol/L。可逆的质子转移检测机制赋予S循环再利用的优势，借助于检测试纸，实现了CN-可逆的比色检测。该工作为纯水相中CN-的检测提供了实验依据。 |
| 英文摘要: |
| A water-soluble colorimetric sensor (S) was well designed and synthesized,and its structure was characterized by 1H NMR, ESI-MS. In pure water and tap water, S displayed exclusively selectivity for CN- with the detection limits of 0.16μmol/L and 0.63μmol/L, respectively. The detection mechanism of proton transfer was fully reversible, which endows the advantage of reusability of S. The reversible colorimetric detection of CN- could be achieved based on the test strip. This work may provide a feasible experiment reference for CN- detection in pure water. |
