An Amperometric Biosensor Based on Alanine Dehydrogenase for the Determination of Low Level of Ammonium Ion in Water
Figure 2
Cyclic voltammograms of AlaDH electrode in the absence (a) and presence (b) of 1.70 mg/L ion. The experiment was conducted in the presence of 0.3 mM pyruvate and NADH at pH 7 with a scan rate of 0.02 V/s versus Ag/AgCl electrode.
