Kinetics of Photooxidative Degradation of Pesticides in Water

Water contaminated by pesticides presents a severe problem due to their generally high solubility in water, low-sorption affinity to soils, toxicity, chemical stability, bioaccumulation and low biodegradability. Directive 2013/39/EU is promoting preventive actions, identifying pollution causes, dealing with emissions of pollutants at the source, and development of innovative (waste)water treatment technologies. This document includes a list of 45 substances or groups of substances and other pollutants with defined environmental quality standards, requiring attention due to their high frequency of occurrence, the expected risk for human health and aquatic life . Seven pesticides included in the list of priority substances have been chosen as targeted water pollutants in this study: alachlor, atrazine, chlorfenvinphos, cybutryne, diuron, isoproturon and simazine. The conventional water treatment technologies, mostly relying on physical and biological processes, seem to be inadequate for effective removal of priority substances such as pesticides, while advanced oxidation processes showed a good performance for the same purpose. The aim of the study was to determine degradation kinetics of targeted pesticides in water, evaluate and compare the effectiveness of photooxidative AOPs, UV-C/H2O2 and UV-C/S2O82-. Response surface modeling was used as a tool for screening the influence of key process parameters: pH and pollutant/oxidant ratio, on the process effectiveness, and for determining the optimal conditions within the investigated range. In addition, the inhibitory influence of NOM on the degradation of PSs in the mixture was determined.
