THE MECHANISTIC STUDY OF PLASMA ACTIVATED SOLUTION ON OTHER CHEMICALS

Abstract

Plasma activated solution (PAS) is recently emerging as a novel medium for non-toxic chemical decontamination of agricultural products. The active radicals especially hydroxyl free radicals (•OH) are reported to effectively and rapidly degrade chemicals to harmless substances. Various researches were investigated on the effectiveness of PAS for chemical residues removal from contaminated agricultural products, but little is known about their mechanism and kinetic. This study will observe degradation mechanism of three representatives from distinct pesticide classifications with extensive usage in Thailand, namely Diuron, Carbosulfan and Carbendazim. Degradation pathways along with their kinetics will be obtained based on the 2 optimized PASs from pin-hole plasma jet. The resulting chemical reaction will be used in establishing the numerical model, which will be simulated, optimized and validated. Fundamental knowledge gained from this project could propel us to invent a suitable prototype for decontamination of pesticides that can be potentially and extensively utilize to help many aspects of food safety worldwide.
