摘要
在pH 4.4～5.0的HAc-NaAc介质中,盐酸普罗帕酮(PPF)能与赤藓红(Ery)阴离子形成离子缔合物,引起荧光猝灭。赤藓红(Ery)体系用荧光猝灭法测定盐酸普罗帕酮的检出限分别为:0.045μg?mL-1而线性范围分别为:0.5～3.5μg·mL-1。本实验重点研究了荧光猝灭法的适宜反应条件。
In pH 4.4～5.0 HAc-NaAc buffer medium,Propafenone Hydrochloride（PPF） could react with Ery to form ion-associations which resulted in the fluorescence quenching of Ery.The fluorescence quenching intensity was proportional to the concentration of PPF in the rang of 0.5～3.5 μg？mL-1 for Ery systems,and the detection limits（3σ） were 0.045 μg·mL-1.The optimum reaction conditions were investigated.
