AB  - Non-equilibrium atmospheric pressure plasmas (APP) are chemically active media with properties adjustable to comply with various application demands. ln biomedical field, so far APP have demonstrated excellent applicability in sterilization and cleaning, i.e. for treatment of organic materials and microorganisms. Atmospheric pressure plasma jets (APPJ) proved to be technically simple and efficient sources of cold APP which are suitable for different application setups. Recently, a new research field-plasmas in agriculture emerged, widening number of applications. Since APPJs can also operate in contact with liquids, they are suitable for new applications in plasma agriculture. Initial investigations show that chemically reactive environment produced by these sources can influence and modify physical and chemical properties of liquids. As one of the main surface water contaminants are pesticides used in agriculture our idea is to use APP for water detoxification. Namely, we conducted a study on decontamination of water samples polluted with different pesticides, i.e. organophosphate compounds, by using APPJs. We used two different jet configurations powered by a kHz signal source with He as working gas and treated liquid samples at different distances between the jet and the sample surface, for different duration times and for different liquid sample volumes. Optical and electrical characterization of the APPJs is performed in order to obtain information about the plasma properties and stability of the treatment conditions. Liquid sample analysis before and after the treatment are executed by using high performance liquid chromatography (HPLC) and liquid chromatography coupled with mass spectrometry (LC-MS) in order to follow degradation of organophosphates. Significant and efficient degradation of both pesticides is noticed and appearance of degradation products is observed in the liquid sample. Dependence of the decontamination efficiency on treatment time is determined. We also investigated toxicity of degradation products. Thus, from the data obtained we could assess the decontamination efficiency for different APPJ types and also to provide information about mechanisms governing the plasma destruction of organophosphates.

AB  - Nonequilibrium atmospheric pressure plasma proved to produce reactive chemistry environment at gas temperatures as low as room temperature which is perfect for treatments of different kind of surfaces. Over the past several years cold atmospheric pressure plasma applications in surface sterilization and cleaning have been extensively studied. Recently, the research has been directed to utilization of this type of plasma far agriculture. Plasma is used directly for treatment of seeds, but, also, indirectly through plasma activated water. In the case of decontamination of water contaminated with conventional pesticides and insecticides plasma can play important role. One of suitable plasma sources for these treatments are atmospheric pressure plasma jets (APPJ), since they are small-size (easily scalable to larger systems), relatively technically simple and cost-effective devices. In our case, we investigated treatments of water contaminated with three types of pesticides. Decontamination is achieved by applying the jet on the liquid surface generating high-energy electrons, reactive oxygen and nitrogen species, radicals and ultraviolet radiation. Reactive species created al the gas-liquid interface effectively degrade organic pollutants in the water. However, due to the complexity of the system, key mechanisms important for destruction of particular contaminant are not clearly known. Moreover, optimisation of the system is recondite by reciprocal influence of the jet and surface. Thus, we have performed detailed and systematic investigation of the APPJ-liquid sample system properties at different conditions and far different pollutants dissolved in water. Electrical and optical measurements provided information about the discharge running at different powers and distances from the sample. We could relate electrical characteristics with spatial profiles of the discharge. Moreover, optical spectrometry provided data on emission lines characteristic far the plasma used far decontamination. By using liquid chromatography measurements of contaminated water samples before and after the treatment we acquired evidence on destruction of specific pollutants and found decontamination rates. AII this data is valuable far evaluation of APPJ efficiency at different operating conditions and optimisation of the decontamination process.
