新型1,2,4-三唑重金属离子荧光淬灭剂的合成、表征与性能
Synthesis, Characterization and Properties of Novel 1, 2, 4-Triazole Heavy Metal Ion Fluorescence Quencher
摘要
Abstract
To find out a novel fluorescent quencher that may rapidly detect and remove heavy metal ions , a series of heavy metal (Co, Cr, Mn, Ni) complexes with 4-amino-3,5-bis (o-hydroxyphenyl)-1, 2, 4-triazole as ligand were synthesized. Their structures and coordination modes were confirmed by IR , 1 H NMR, 13 C NMR, MS and element analysis .The TGA, ultraviolet spectra and fluorescence quenching properties were also discussed .The results showed these complexes had good thermal stability .The Mn and Ni complexes were decomposed into stable oxide at high temperatures .The UV absorption intensity of the complexes was weaker than that of the ligand .The fluorescence of ligand was quenched when the ligand was coordinated with metal ions, which indicated heavy metal ions (Co, Cr, Mn, Ni) are good fluorescence quenchers for 1, 2, 4-triazole ligand and could be removed as precipitate .关键词
