Abstract: This paper aims to explore the use of wire-tube DBD reactor for the treatment of atrazine in soil, and to investigate the influence of relevant factors on the degradation efficiency of atrazine. The discharge voltage, air flow rate, soil particle mesh, initial atrazine concentration, soil moisture content, Fe 2+ concentration (based on the optimal soil moisture content condition) and glycine concentration on the degradation of atrazine in soil were investigated. The results showed that: increased the discharge voltage and soil particle mesh could improve the degradation efficiency of atrazine; increased the air flow rate, the initial atrazine concentration and the glycine concentration in the soil could inhibit the degradation efficiency of atrazine; and increased appropriately the soil water content and the Fe 2+ concentration (FeCl 2 ) could help to improve the degradation efficiency of atrazine. Under the multiple influence factors optimization conditions, the degradation efficiency of atrazine in soil reached 92.48% when the reaction time reached 24 min. Finally, the degradation products of atrazine under the single system of atrazine and the composite system of atrazine and glycine as well as the inference of the degradation pathways were analyzed by high-resolution mass spectrometry (HRMS), and it concluded that there were more kinds of atrazine degradation products under the single system than in the composite system but the products were not completely contained, and the degradation pathways of atrazine in the single system were more than those in the composite system.

Description
Abstract:This paper aims to explore the use of wire-tube DBD reactor for the treatment of atrazine in soil, and to investigate the influence of relevant factors on the degradation efficiency of atrazine. The discharge voltage, air flow rate, soil particle mesh, initial atrazine concentration, soil moisture content, Fe <sup>2+</sup> concentration (based on the optimal soil moisture content condition) and glycine concentration on the degradation of atrazine in soil were investigated. The results showed that: increased the discharge voltage and soil particle mesh could improve the degradation efficiency of atrazine; increased the air flow rate, the initial atrazine concentration and the glycine concentration in the soil could inhibit the degradation efficiency of atrazine; and increased appropriately the soil water content and the Fe <sup>2+</sup> concentration (FeCl <subscript>2</subscript> ) could help to improve the degradation efficiency of atrazine. Under the multiple influence factors optimization conditions, the degradation efficiency of atrazine in soil reached 92.48% when the reaction time reached 24 min. Finally, the degradation products of atrazine under the single system of atrazine and the composite system of atrazine and glycine as well as the inference of the degradation pathways were analyzed by high-resolution mass spectrometry (HRMS), and it concluded that there were more kinds of atrazine degradation products under the single system than in the composite system but the products were not completely contained, and the degradation pathways of atrazine in the single system were more than those in the composite system.
