Establishing a reaction model of the irradiated carbon tetrachloride/water system

Creators

Description

Quite a number of radicals affecting the whole reaction mechanism up to the end products HCl and CO2 in a manifold way are to be taken into account when considering the irradiation system CCl4-H2O. The simultaneous increase in H+ ion concentration can be determined by means of conductivity measurements. By varying parameters such as pH-value, temperature and concentration, the effect of radiation dose is studied. Within the overall process, the system CO2/water as a relaxation system is of particular importance and is given special attention in the thesis. A reaction model of the overall process is established and supplemented by mathematical approximations. These approximations are shown in tables and are compared with data obtained by other authors.

Abstract (German)

Im Bestrahlungssystem CCl4-H2O spielen eine ganze von entstehenden Radikalen eine Rolle, die den gesamten Reaktionsablauf bis hin zu den Endprodukten HCl und CO2 in vielfaeltiger Weise beeinflussen. Die gleichzeitig resultierende Erhoehung der H+-Ionenkonzentration laesst sich durch Leitfaehigkeitsmessung ermitteln. Unter Variation der Parameter pH-Wert, Temperatur und Konzentration wird der Einfluss der Strahlungsdosis untersucht. Im Gesamtprozess spielt das CO2/Wasser-System als Relaxationssystem eine besondere Rolle und wird naeher untersucht. Es wird schliesslich ein Gesamtreaktionsmechanismus aufgestellt und mathematisch approximiert. Die Ergebnisse der Approximationen sind tabellarisch aufgefuehrt und werden mit denen anderer Autoren verglichen. (RB)
