英文摘要	利用一种罗丹明衍生物荧光探针的开环效应检测Hg2+.在PH 7.0的TrIS-HCl缓冲液中,Hg2+与荧光探针结合导致罗丹明类衍生物开环,溶液颜色由无色变成粉红色,并且发射强的荧光.荧光强度与Hg2+浓度在20~200 ng/l范围内呈良好的线性关系,检出限为4 ng/Ml.实验考察了荧光探针的选择性以及温度、PH、荧光试剂浓度和盐度对Hg2+检测的影响.结果表明该方法具有反应试剂水溶性好、选择性好和可常温检测等优点.方法应用于自来水、河水和湖水等水体中Hg2+的检测,获得较好的回收率.; The fluorescence enhancement of rhodamine derivative(RHD-1) was applied to the determination of Hg2+in water samples.Mercury ion interacted with the fluorescent probe in Tris-HCl buffer solution at pH 7.0,leading to the opening of RHD-1 structure,resulting in high fluorescence emission and the change of solution color.The fluorescence intensity was in proportion to the concentration of Hg2+ very well in the range of 20–200 ng/L,and the detection limit was found to be 4 ng/L.The effects of temperature,pH and the concentration of fluorescent reagent on the sensitivity and selectivity were investigated.The method was applied to detect Hg2+ in tap and lake water samples.The obtained result and sample recovery were all satisfactory.; 福建省质量技术监督局项目(FJQI2011014); 国家自然科学基金(20975085)资助
