One-step synthesis of porous copper oxide for electrochemical sensing of acetylsalicylic acid in the real sample.

A Facile approach of one-step synthesis was employed to prepare porous CuO at different annealing temperature and characterized by using numerous analytical techniques. Moreover, the electrochemical sensing application of CuO modified glassy carbon electrode was studied and recorded using various electrochemical techniques. From the results, it was interpreted that the CuO prepared at 350°C exhibits satisfactorily electrochemical determination of Acetylsalicylic acid (ASA) with unique sensitivity, linear range and limit of detection of about 831.65µA mM-1 cm-2 , 0.1-714µM and 0.037µM respectively. The proposed sensor also shows good electrocatalytic performance in real sample analysis with acceptable results.
