EFFET DES PARAMETRES REACTIONNELS SUR LA CHLORATION DE l’HISTIDINE EN EAUX MINERALISEES

Abstract

The aim of this work is to study the chlorination of histidine (nitrogenous base) in media of various mineralizations (distilled water and ground water). Several reaction parameters (effect of pH, contact time, chlorination rate) were tested during the chlorination of histidine. The results obtained showed that histidine remains reactive with the chlorine whatever the mineralization of the medium. They showed also that the pH affects the chlorination of histidine and the acid pH always favors its reactivity. Similarly, the contact time has an effect on the reactivity of chlorine consumption by dividing it into two steps, one fast and the other slow.
