Abstract The ultra race amount of amphetamine was efficiently measured using the fluorescence probe based on 8-hydroxyquinoline-β-cyclodextrin. The absorption spectra were obviously proved the static enhancement mechanism of the probe under the response time, 50 s and solution pH, 6 as optimized conditions. 8-hydroxyquinoline-β-cyclodextrin-graphene oxide (GO-CD-HQ) showed an excellent response to amphetamine in the linear concentration range (1–140) × 10−5 M, with a notable detection limit 3.67 × 10−5 M.

使用接枝在氧化石墨烯上的 8-羟基喹啉-β-环糊精对苯丙胺进行高灵敏度荧光测量

摘要 使用基于8-羟基喹啉-β-环糊精的荧光探针有效地测定了苯丙胺的超外消旋量。吸收光谱明显证明了探针在响应时间50 s和溶液pH 6为优化条件下的静态增强机制。8-羟基喹啉-β-环糊精-氧化石墨烯 (GO-CD-HQ) 在线性浓度范围 (1–140) × 10−5 M 内对苯丙胺表现出极好的响应，显着的检测限为 3.67 × 10−5 M .
