Macrokinetic Model of Catalase Electrode with Biphasic Enzyme Inhibition

Macrokinetic Model of Catalase Electrode with Biphasic Enzyme Inhibition

Macrokinetics of catalase based enzyme electrode was investigated in presence of enzyme inhibitor – hydroxylamine. The modeling of the electrode was performed using biphasic scheme of enzyme inhibition and external diffusion limitation. The maximal enzyme electrode sensitivity was indicated at tran...
