研制了一种基于PET工艺的荧光传感器，该传感器在乙腈- h2o缓冲溶液中对Cd（2+）的检测限为1.9 × 10(-12) mol L(-1)，在pH为3.5的纯水中对Cu（2+）的检测限为4.9 × 10(-9) mol L(-1)，检测限为1.9 × 10(-12) mol L（-1）。
A fluorescent sensor L, which showed turn-on response towards Cd(2+) with a detection limit of 1.9 × 10(-12) mol L(-1) in acetonitrile-H2O buffer solution based on the PET process and turn-off response toward Cu(2+) with a detection limit of 4.9 × 10(-9) mol L(-1) in pure water at pH 3.5 based on electrostatic effects, was developed.
