A fluorescent dye, 9-anthraldehyde-thiosemicarbazone (AnthT), used for the determination of Cu(II) or Hg(II) in aqueous solutions, is described. The fluorescence intensity of the probe decreased with increasing concentration of Cu(II) or Hg(II), and was proportional to a certain concentration of Cu(II) or Hg(II). The prepared sensing system presented satisfactory sensitivity and low detection limits. The developed method was successfully employed for preliminary application in natural water and domestic sewage.
描述了一种用于测定水溶液中铜（II）或汞（II）的荧光染料9-蒽甲醛缩氨基硫脲（AnthT）。该探针的荧光强度随铜（II）或汞（II）浓度的增加而降低，并与一定浓度的铜（II）或汞（II）成正比。所制备的传感系统具有令人满意的灵敏度和低检测限。所开发的方法成功地应用于天然水和生活污水的初步检测。
