Abstract

Svrha ovog rada bila je utvrditi potencijal tretmana hladnom plazmom pri razgradnji fungicida (fenheksamida). U ovom radu su primijenjene tri različite izvedbe hladne plazme i uspoređena je njihova učinkovitost. Primijenjene izvedbe uključivale su plazmu JET (Ar), hibridnu plazmu (Ar i O2) te plinsku plazmu (Ar i O2). Primjena hibridne plazme se pokazala iznimno učinkovitom uz oba radna plina tijekom 30 minuta tretmana, međutim primjenom argona postignuti su najbolji rezultati razgradnje (99,90% razgradnje fenheksamida) za razliku od tretmana kisikovom plazmom (81,33%). Kod tretmana plinskom plazmom najbolji rezultati su postignuti kisikovom plazmom (99,89% razgradnje), nego u slučaju primjene argona (65,24% razgradnje). Primjenom plazma JET tretmana također su postignute visoke vrijednosti razgradnje fungicida (98,35% razgradnje fenheksamida), međutim kroz dulje vrijeme tretiranja od 60 minuta. Dobiveni rezultati potvrđuju iznimnu učinkovitost sva tri primijenjena plazma tretmana pri degradaciji fenheksamida.

Abstract (english)

Main goal of this research was to determine the potential for nonthermal plasma treatments on decomposition of fungicide (fenhexamid). Three different plasma treatments have been used in this research and compared on their efficacy. The applied plasma designs included: plasma JET (Ar), hybrid plasma (Ar and O2) and gas-phase plasma (Ar and O2). The use of hybrid plasma has been extremely effective with both gases (Ar and O2) during 30 minutes of treatment, however use of Ar plasma achieved the best degradation results (99.90% degradation of fenhexamid) as opposed to oxygen plasma treatment (81.33%). In gas-phase plasma treatment, the best results were achieved with oxygen plasma (99.89% degradation) compared to Ar plasma (65.24% degradation). High fungicide degradation rates of (98.35% decomposition of fenhexamid) were also achieved using plasma JET treatment, but during a longer treatment time of 60-minutes. The obtained results confirm the exceptional efficacy of all three plasma treatments at fenhexamid decomposition.
