[Objective] The aim was to establish a detection method for 8-hydroxyquinoline Copper. [Method] Using the self-made acridone derivative 10-methyl-3-nitro-acridone( MAT) as an enhanced fluorescence signal probe,a method for determination of 8-hydroxyquinoline copper was established. [Result] Under the optimal conditions,the value of fluorescence enhancement showed a good linear relationship with the concentration of 8-hydroxyquinoline copper in the range of 5 × 10-9to 5 × 10-5mol / L,and the detection limit ...
