ABSTRACT
Mousavi SM, Imani S, Dorranian D, Larijani K, Shojaee M., Dielectric barrier discharge degradation of diazinon in vegetables, Onl J Vet
Res., 19(11): 755-761,
2015. A non thermal gas
nanosecond discharge inserted through dielectric barriers (DBD) can release
particles from an object. Diazinon concentrations
before and after DBD treatments of cucumber samples were detected by HPLC.
GC/MS chromatography was performed to determine metabolites formed by DBD
treatments. Results suggested that DBD 13 (10) kV air plasma reduced diazinon concentration from 600 to 300ppm and 350 to 50ppm
after 10 minutes without deformation or any other side effect. Increasing
voltage of DBD decreased treatment time. The treatment may have decomposed diazinon to 2-isopropyl-6-methyl-4-pyrimidinol (IMP) and diazoxon.
Keywords: Diazinon, Non-Thermal Plasma, Degradation, GC/MS.
