摘要

Abstract

Atrazine (ATZ) is a highly applicable neurogenic herbicide in crops. Due to its triazine structure

ATZ is durable in nature and difficult to degrade

posing serious environmental and health threats. In this work

a rotating packed bed reactor integrated with plasma(plasma-RPB)was employed to degrade ATZ. The effects of operating conditions and typical water matrix components were systematically evaluated. Results demonstrated that increasing rotational speed and discharge power enhanced degradation efficiency

while higher initial ATZ concentrations inhibited removal. Among common water matrix species

and Cl

exhibited inhibitory effects

significantly suppressed degradation

showed little impact. Ultra performance liquid chromatography-mass spectrometry analysis revealed that ATZ was mainly degraded

via

dealkylation and hydroxyl substitution

producing cyanuric acid and eventually undergoing ring opening. To enhance process robustness against inhibitory water matrices

peroxymonosulfate (PMS) integration was investigated as an intensification strategy. Utilizing the multiple activation pathways in the plasma environment

PMS was effectively activated to generate additional sulfate radicals. Under optimized conditions

degradation efficiency and total organic carbon removal of actual industrial wastewater reached 99% and 90% within 20 min

respectively. This study highlights plasma-RPB

particularly when synergized with PMS

as a promising technology for pesticide wastewater treatment.
