Název v původním jazyce

Experimental study of enzymatic oscillatory reaction

Popis výsledku v původním jazyce

This work is focused on experiments with the glucose - catalase - glucose oxidase - hydrogen peroxide reaction carried out in a batch and continuous-flow stirred tank reactors. This reaction belongs to the large family of enzymatic oscillatory reactionsoften found in biological systems. The experimental setup consists of two separate cells connected via a dialysis membrane. The first cell contains hydrogen peroxide which permeates through the membrane to the second cell. The second cell contains catalase, which catalyzes production of oxygen, and glucose oxidase, which catalyzes oxygen consumption. The time variation of dissolved oxygen concentration in the reaction solution is measured by an inserted oxygen electrode. The aim of this work is to verify an oscillatory course of dissolved oxygen concentration in this enzymatic system reported in literature and a parametric study of dependence on mixing, temperature and initial concentrations of components (hydrogen peroxide, glucose, ca
