Bench- and pilot-scale studies on the removal of pesticides from water by VUV/UV process

Removal of pesticide residues from fresh vegetables by the coupled free chlorine/ultrasound process

“…The concentration of pesticides was determined by ultra-performance liquid chromatography-tandem mass spectrometry (UPLC/MS/MS, Xevo TQD, Waters, USA) [18] , [19] . The injection volume was 10 μL.…”

Photolysis for the Removal and Transformation of Pesticide Residues During Food Processing: A State-of-the-Art Minireview

“…It was mainly due to VUV at 185 nm could produce more energetic photons. Additionally, Yang et al investigated the removal of five typical pesticides from water by VUV/UV at both bench- and pilot-scale studies ( 5 ). Results showed that VUV/UV showed much more effective and energy-efficient than UV and all pesticides could be removed with an efficiency of >90% at a VUV fluence of 12 mJ/cm 2 .…”

“…Some amounts of pesticide residues could remain on foods such as vegetables and fruits that accounted for 30% of an individual’s diet, which is frequently transferred to markets and consumed by humans without proper washing or with minimal processing ( 4 ). Unfortunately, pesticides have been identified as a major problem by a variety of countries because of their persistence in environments and adverse effects on human health, including the destruction of biodiversity, and dermatological, gastrointestinal, neurological, carcinogenic, respiratory, reproductive, and endocrine effects ( 5 – 7 ). Therefore, it is of great significance for the degradation of pesticide residues during food processing.…”

A novel approach to interpret quasi-collimated beam results to support design and scale-up of vacuum UV based AOPs

“…Optimizing a reactor for both the short penetrating VUV and relatively longer penetrating UV is challenging. Most of the laboratory-scale configurations, like quasi -collimated beam apparatus ( q CB) ( Baeza and Knappe, 2011 ; Duca et al., 2017 ; Fang et al., 2014 ; Feng et al., 2007 ), annular reactors ( Ngouyap Mouamfon et al., 2011 ; Zhan et al., 2021 ; Zoschke et al., 2012 ) and micro-fluidic vacuum UV reactors ( Yang et al., 2018 ) employed in VUV research have small mean reactor pathlengths that favorably uses VUV over UV. Despite extensive research published using laboratory-scale VUV reactors, there are scarce applications of VUV reported at pilot-scale ( Krakko et al., 2021 ).…”
