Liu, Yuanyuan; Li, Yi; Zong, Linghui; Zhang, Jingyi published the artcile< Comparison of two rhodamine-based polystyrene solid-phase fluorescent sensors for mercury(II) determination>, Application In Synthesis of 950846-89-6, the main research area is rhodamine based polystyrene microsphere fluorescent sensor mercury ion determination.
Two novel rhodamine-based polystyrene solid-phase fluorescent sensors PS-AC-I and PS-AC-II with different coordination atoms (O or S) are synthesized and shown to be able to detect Hg(II) ions. They are characterized by Fourier-transform IR spectroscopy and by SEM anal. Their fluorescent properties, including response time, pH effects, fluorescence titrations, metal ion competition and recycling, are investigated and compared. Sensor PS-AC-II displayed higher selectivity and sensitivity to Hg(II), with a lower detection limit of 0.032μM, which was 15 times better than PS-AC-I. A detection mechanism involving the Hg(II) chelation-induced ring-opening of the rhodamine spirolactam is proposed with the aid of theor. calculations
