Nghiên cứu cơ chế của quá trình peroxydasa trong hệ H2O-Ni2+-HCO3--Lm-H2O2 (1)

Abstract

By using method of using inhibitor, it was found that the catalytic process of indigocarmine (Ind) oxidation take place according to the radical chain mechanism with a generation of free active OH^* radical reacting with Ind, H₄L, In (Lumomagnezone  - Lm, Hydroquinon - Hq, Paranitrozodimetylanilin - Pa) in the systems:

H₂O - Ni²⁺ - HCO₃^-- Lm - Ac -H₂O₂ (2)

H₂O - Ni²⁺ - HCO₃^-- Lm  - Hq -H₂O₂ (3)

H₂O - Ni²⁺ - HCO₃^-- Lm - Pa -H₂O₂ (4)

This article presents our results of calculating the rate constant k(Ind+OH*) of oxidizing reaction of Indigocarmine by hydroxyl radicals OH*. k(Ind + OH*) was calculated by using Turbopascal programming languages.

Keywords. Inhibitor, indigocarmine, hydroxyl radicals.
