Survey of kinetics of spontaneous ozone decay in water

In the general part of this diploma thesis are presented technical information collected on the issue of spontaneous decay of ozone in water solution and problems with analytical monitoring of these processes. Particular attention is paid to influence of pH value, bicarbonate and peroxide concentration on ozone decay kinetics. Experimental part is focused on the use of spectrophotometry in the study of chemical reactions associated with the spontaneous decay of ozone in distilled and tap water depending on pH and temperature after saturating of water by ozone prepared from air and pure oxygen. Direct photometry in UV range of spectrum (at 260 nm) was used to monitoring of ozone decomposition kinetics
