(a) CVs of electropolymerization of CS@Pt NCs on GCE (n = 5 cycles, scan rate = 100 mV/s) and (b) CVs of Mn(TPDCA)2/Pt NCs/poly-CS/GCE modified electrode phosphate buffer as supporting electrolyte (I), Mn(TPDCA)2/Pt NCs/poly-CS/GCE (II) in the 25 mg/L AMD, and 50 mg/L AMD (III) in the phosphate buffer as supporting electrolyte (50 mM, pH 7.5)
