摘要

This work reports the electrochemical determination of acebutolol (ACE) by the screen printed carbonelectrode (SPCE). Before the determination, the SPCE was activated by the electrochemicalpretreatment. This pretreatment creates the edge plane active sites on the SPCE surface and also itcreates the electrochemically active functional groups. The activation process was confirmed by theRaman, SEM and electrochemical analysis. The activated SPCE (aSPCE) revealed the betterelectrochemical performance when compared with SPCE. It is presumed that, this remarkableperformance was obtained from the edge plane active sites and the electrochemically active functionalgroups (such as carbonyl groups and hydroxyl groups). Further, this aSPCE utilized to the ACEdetermination in phosphate buffer solutions which received a great significance of analyticalperformances. It revealed the good sensitivity (1.02 μA mM -1 cm -2 ), linear range (0.01 to 200 μM) andlow LOD (0.006 μM). Moreover, it shows significant anti-interference properties in suspectedinterfering compounds.
