A simple and sensitive method for the determination of propranolol using modified screen printed carbon electrode (MSPCE) has been presented. The electrochemical measurements of propranolol are studied using differential pulse voltammetry (DPV), cyclic voltammetry (CV) and chronoamperometry (CHA). The MSPCE exhibite excellent catalytic activity towards electrochemical oxidation of propranolol in phosphate buffer solution (PBS) of pH 7.0. The MSPCE facilitate the determination of propranolol in the concentration range 0.4 – 200.0 μM and a detection limit and sensitivity of 80 nM and 0.052 μA/μM has been achieved.

修饰丝网印刷电极电化学测定普萘洛尔

提出了一种使用修饰的丝网印刷碳电极（MSPCE）测定普萘洛尔的简单而灵敏的方法。使用微分脉冲伏安法（DPV），循环伏安法（CV）和计时电流法（CHA）研究了普萘洛尔的电化学测量。MSPCE在p H 7.0的磷酸盐缓冲溶液（PBS）中对普萘洛尔的电化学氧化具有极好的催化活性。MSPCE有助于测定浓度范围为0.4 – 200.0μM的普萘洛尔，并且检出限和灵敏度分别为80 nM和0.052μA/μM。
