RESUMEN
Dansyl Chloride (DNS-Cl) was used as a phosphorescent labeling agent for the determination of practolol. The derivative was formed by refluxing practolol-ethyl acetate solution with the solid DNS-Cl in the presence of potassium carbonate anhydride. Room-temperature phosphorescent (RTP) properties of the derivative were studied by a micelle-stabilized room-temperature phosphorescence (MS-RTP) method. Phosphorescence lifetimes of practolol-DNS and the DNS-Cl were found to be 0.791 and 0.408ms, respectively. By applying the derivative MS-RTP technique, practolol could be quantitatively determined without previous separation process. Detection limit of practolol with the proposed method was 0.19 microg/mL.
