Cyclic voltammograms of the electrode modified with Ag/MWCNTs/pAAQ/CPE in a solution of 0.1 M HCl for 5 sampling cycles at a sampling rate of wereV s−1 in a potential range from − 0.2 to 1.4 V with a switching potential at − 0.2 V. The step is the subsequent step after applying a fixed potential of 0.75 V for 2 min with stirring.
