Abstract
Cilj ovog rada bio je proizvesti plazma aktiviranu vodu (PAW) dobivenu primjenom visokonaponskog plazma pražnjenja te okarakterizirati plazma reaktor s kombiniranim pražnjenjem. Tijekom procesa određivani su fizikalno-kemijski parametri destilirane vode tretirane hibridnom plazmom. Uzorak vode tretiran je pri različitim frekvencijama (60 Hz, 90 Hz i 120 Hz) uz upuhivanje dvije vrste radnog plina: argon i kisik. Također, parametri su mjereni u različitim vremenskim intervalima od 5 i 10 minuta. Najviše vrijednosti temperature (46,2 ℃) i pH (2,60) dobivene su pri 120 Hz nakon 10 minuta tretmana kada se kao radni plin koristio argon, dok je najveća električna provodljivost (220,7 μScm-1) izmjerena nakon 10 min tretiranja pri 60 Hz. Koncentracije vodikova peroksida, nitrita i nitrata imale su veće vrijednosti u tretmanu tijekom kojeg se upuhivao kisik.
Abstract (english)
The aim of this study was to produce plasma activated water (PAW) obtained by applying high-voltage plasma discharge and to characterize the plasma reactor with combined discharge. During the process, physico-chemical parameters of distilled water treated with hybrid plasma were determined. The water sample was treated at different frequencies (60 Hz, 90 Hz and 120 Hz) with two types of working gas: argon and oxygen. Also, the parameters were measured at different time intervals of 5 and 10 minutes. The highest temperature values (46,2 ℃) and pH (2,60) were obtained at 120 Hz after 10 minutes of treatment when argon was used as working gas, while the highest electrical conductivity (220,7 μScm-1) was measured after 10 min of treatment at 60 Hz. Hydrogen peroxide, nitrite and nitrate concentrations had higher values in treatment during which oxygen was injected.
