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).
