摘要:

以苯磺酰肼和1-芘甲醛为原料,设计合成了一种结构简单的可快速识别汞(Ⅱ)离子(Hg2+)的磺酰腙型荧光探针(Z)-N'-(芘-1-基亚甲基)苯磺酰腙(BSB),并通过氢核磁共振波谱仪(1H NMR)对其结构进行了表征。BSB对Hg2+展示出高选择性、专一性和快速响应性,检测限为2.07×10-7 mol/L,响应时间仅需15 s。通过job's曲线,1H NMR滴定实验和高分辨率质谱(HRMS)对响应机理进行了探究,并且BSB可以检测不同水样中的Hg2+。有趣的是,将BSB和聚丙烯酰胺(PAM)相掺杂制备出了对Hg2+具有高去除性能的新型高分子材料(PAM?BSB),去除率达到99.63%,并通过扫描电子显微镜(SEM)对PAM?BSB吸附前后的微观形貌进行了观察。

Abstract:

A simple fluorescent probe (Z)-N'-(pyrene-1-ylmethylene) benzenesulfonylhydrazone (BSB) was designed and synthesized by using benzenesulfonylhydrazine and 1-pyrene-formaldehyde as materials, and its structure was characterized by hydrogen nuclear magnetic resonance spectroscopy (1H NMR). BSB shows high selectivity, specificity and rapid response to Hg2+. The detection limit is 2.07×10-7 mol/L, and the response time is only 15 s. The optimal response mechanism is explored through job's curve, 1H NMR titration experiment and high resolution mass spectrometry (HRMS). BSB could detect Hg2+ in different water samples. Interestingly, a novel polymer material (PAM?BSB) with high Hg2+ removal performance is prepared by doping BSB with polyacrylamide (PAM). The removal rate is 99.63%, and the micro-morphology of PAM-BSB before and after adsorption is observed by scanning electron microscopy (SEM).
