将荧光试剂荧光素共价连接于聚氯乙烯支链上,首次合成了一种具有荧光敏感功能的高分子材料,用该敏感材料为敏感膜的铜离子荧光熄灭型传感器使用寿命显著延长,对铜离子的检测范围与检测下限分别是2.5×10~(-5)～1.O×10~(-3)mol/L和1.0×10~(-6)mol/L。
Fluorescent reagent fluorescein covalently attached to the branch of polyvinyl chloride, the first synthesis of a fluorescence-sensitive polymer materials, the sensitive material as a sensitive membrane copper ion fluorescence quenching sensor life significantly extended, the The detection range and the detection limit of copper ions were 2.5 × 10 -5 mol -1 and 1.0 × 10 -6 mol / L, respectively.
