Synthesis and assessment of glycosylrhodamine-based fluorescent probe for the rapid detection of heavy metal mercury ion

目的建立快速测定重金属汞离子的方法。方法合成糖基罗丹明荧光探针,在糖基罗丹明荧光探针溶液中加入汞离子,其在583 nm处呈现较强的荧光。结果糖基罗丹明荧光探针可应用于快速检测水溶性媒介中的重金属Hg^(2+),而不受Ca^(2+)、Ba^(2+)、Cd^(2+)、Co^(2+)、Mg^(2+)、Ni^(2+)、Zn^(2+)、Na^+、K^+、Ce^(3+)、Cu^(2+)等离子的干扰。结论所用方法所需样品量和时间均较少,简便易行。

OBJECTIVE To establish a rapid detection method for heavy metal mercury ion. METHODS The glycosylrhodamine - based fluorescent（ RB - 1 ） probe was synthesized. The RB - 1 aqueous solution showed a strong fluorescence emission at 583 nm after addition of mercury ion. RESULTS This probe could be applied to the rapid detection of Hg2 ＋ in solution. It would not be intefferred by Ca2 ＋ , Ba2 ＋, Cd2 ＋ , Co2 ＋ , Mg2＋ , Ni2 ＋ , Zn2 ＋ , Na＋ , K ＋ , Ce3 ＋ , Cu2＋ , and etc. CONCLUSION This method requires less sample and shorter time, and it is easy to control.
