Comparative Study on the Remediation of Fluridone‐Contaminated Soil by Fluidized Bed DBD Plasma

ABSTRACT To address the issue of pesticide residue in soil, this study proposed a remediation strategy combining discharge plasma and fluidized bed technology for the treatment of fluridone (FLU)‐contaminated soil. Under fluidized bed conditions, FLU degradation in soil increased by 12.6% after 10 min of treatment. At a modulated pulse voltage of 20 kV, 50% duty cycle, and 200 Hz, 97.6% of FLU was removed after 12 min of plasma treatment. The order of bond breaking between atoms was determined by Gaussian calculations of the Fukui function and FLU bond energies. Degradation products were identified using Liquid Chromatography‐Mass Spectrometry (LC‐MS), and possible degradation pathways were proposed. This study highlights the advantages of fluidized bed technology in plasma‐based soil remediation.
