Sažetak
Since the day when pesticides were created and began to use them, they became pollutant because of theirs extremely low biodegradability. Although, pesticides have a lot of positive properties, once they enter into the aquatic system, they become a problem. Due to these harmful effects, both on humans and on the flora and fauna, some pesticides are listed on the list of priority substances of Directive 2013/39/EU with purpose to be continuously monitored in the aquatic environment. Therefore, there is a need for finding effective, but also environmentally acceptable methods for their removal. Methods for the primary and secondary wastewater treatment processes are not effective for the removal of pesticides, so Advanced Oxidation Processes (AOP) are showing better efficiency and their potential increases. The aim of this paper was to apply the photolysis and photoxidation processes with the addition of oxidants (hydrogen peroxide and sodium persulphate) in the continuous flow reactor for the removal of pesticide atrazine from model water. The influence of process parameters (flow and concentration of oxidants) on the efficacy of atrazine removal was examined. By using a combination of a full factor plan and the response surface method (RSM), it was found that the maximum removal of atrazine (78.11 %) is achieved by applying a vacuum UV/PS process at a flow rate of 0.6 L/min and a persulphate concentration of 2 mM, which is in accordance with the values of developed RSM model (78.68 %). Also, it has been shown that both process parameters, flow and concentration of oxidants have a significant effect on the effectiveness of the removal of atrazine.
