Abstract :A novel dansyl side-functional polymer insert ignore into journalissuearticles values( P2 ); was prepared and employed as the metal cation sensing chemical probe. The synthesis of P2 was performed via free radical polymerization and esterification reactions in a two-step reaction sequence. P2 showed characteristic UV-vis and fluorescence emission bands for the dansyl unit. The fluorescence emission intensity of P2 gradually decreased as the concentrations of the added metal ions were increased. The highest quenching efficiencies insert ignore into journalissuearticles values(QE); were observed for Pb 2+ insert ignore into journalissuearticles values(84.56%); and Co 2+ insert ignore into journalissuearticles values(83.69%);. Besides, the responses of P2 to the addition of Pb 2+ cation were quite linear up to 50 equivalent. The presence of Cd 2+ , Hg 2+ , Mn 2+ , and Zn 2+ cations did not pose significant interferences. Thus, P2 is a potential candidate for the fluorescence chemical sensor for Pb 2+ cation.
