Water pollution has become a global environmental problem, such as that caused by Pb(II). Therefore, there is an urgent need to develop multifunctional materials for Pb(II) monitoring and removal. Yet, developing bifunctional sensitive detection efficient removal of remain challenging. Here, metal-organic gel (HNU-G4) was constructed sensible responsive adsorption The dry obtained through the freeze-dried process can be used via fluorescence quenching; lowest limit 0.766 ppb. Furthermore, HNU-G4 effective maximum capacity 480.00 mg·g-1 in water. Additionally, demonstrates excellent recoverability interference resistance, which recovery actual reclaimed water samples prevent secondary contamination. This study developed material from water, providing suggested strategy tackle heavy metal contamination problem.
