This thesis aims mainly at investigating the potential oxidizing abilities and possible applications of the UV/Chlorine process as an Advanced Oxidation Process (AOP).
Several organic compounds were used and added into the samples as challenging radical scavengers to investigate the possibilities of the UV/Chlorine process being used in the water and wastewater treatment industry. The UV/H2O2 process was selected as a reference, and experiments were carried out parallel; the results obtained earlier in the UV/Chlorine process were compared to those of the UV/H2O2 process.
Methanol was added into active chlorine solutions at both pH 5 and 10. The quantum yields for the degradation of active chlorine were calculated after the samples had been exposed to UV. Also the production of ∙OH radicals was calculated by determining the generation of formaldehyde. The OH radical yield factors, which are significant in evaluating AOPs, were calculated both in the UV/Chlorine and the UV/H2O2 processes. In addition to methanol, para-chlorobenzoic acid (pCBA) and cyclohexanoic acid (CHA) were added to active chlorine solutions and to H2O2 solutions. The first-order reaction rate constants for the oxidation of pCBA and CHA using the UV/Chlorine process were calculated and compared to those of the UV/H2O2 process. This allowed an evaluation of whether or not the UV/Chlorine process might be efficient for the treatment of contaminated water samples containing pCBA and/or CHA.
Finally the thesis comes to a general conclusion about the efficiency of the UV/Chlorine process compared to that of the UV/H2O2 process.
