Abstract
Pesticides are chemical compounds widely used in crop pest control, ensuring high productivity and product quality control. However, pesticides are toxic and can be bioaccumulative. Their excessive use causes environmental and health impacts. In this study, the potential of glow discharge plasma to degrade diazinon present in water was investigated. For the degradation process, a glow discharge plasma (GDP) system was used to process diazinon at several plasma flow rates (10, 20, and 30 mL/min) and exposure times (10, 20, and 30 min). The degradation levels and the identification of the by-products were analyzed by gas chromatography coupled to mass spectrum (GC-MS). GDP processing efficiently degraded diazinon, reaching a maximum potential degradation of 8.19 ± 0.92 mg/L, sufficient to bring diazinon-contaminated waters to safe levels. Two parallel degradation routes were proposed for diazinon degradation by cold plasma.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
