Abstract
Rapid detection of trace heavy metal ions in water is of great relevance to the environment and human health in the future. With pyrimidine as the parent structure, the water-soluble thiourea group is skillfully introduced to form a symmetric framework, thus firmly capturing the heavy metal ions in the water. The responsiveness of heavy metal ions in water was observed by UV-fluorescence spectroscopy. Especially with Co(NO3)2, Cu(NO3)2, Ni(NO3)2, and Zn(NO3)2, the response changes are most significant. The rapid response changes between them and trace heavy metal ions in water were intuitively observed under sunlight and fluorescence irradiation environment.
