Abstract
U okviru ovoga rada provedena je analiza ponašanja pet različitih membranskih filtara prilikom njihove pripreme za filtraciju uzoraka za određivanje sadržaja otopljenog organskog ugljika (engl. dissolved organic carbon - DOC). Upotrebljeni su membranski filtri nominalne veličine pora 0,45 μm koji se uobičajno koriste za izdvajanje otopljenog organskog ugljika, dijela ukupnog organskog ugljika (engl. total organic carbon - TOC) koji ostaje u otopini nakon filtracije. Pokazano je s kojim će postupkom kondicioniranja membranskih filtara smetnje uzrokovane otpuštanjem organskog ugljika s membrana biti minimizirane i koji je od ispitivanih filtara najbolji za analizu otopljenog organskog ugljika. Provedena su dva tipa ispitivanja: pranje filtara i test namakanja. Tijekom ispitivanja sustavno su uzimani uzorci radi analize koncentracije otopljenog organskog ugljika u vodi i UV apsorbancije na valnoj duljini λ = 254 nm. Najbolje rezultate pokazao je filtar proizvođača Filter Bio, izrađen od polietersulfona prilikom primjene postupka pranja.
Abstract (english)
Five different membrane filters from the three manufacturers were evaluated for dissolved organic carbon (DOC) and ultraviolet (UV254) absorbance measurements. The study was performed to investigate an appropriate method for minimizing interference of organic constituents for DOC determination in filtrated samples. Filters with nominal pore size of 0.45 μm were used to comply with the operational definition of DOC, which is defined as organic carbon, part of the total organic carbon (TOC) remaining in solution after filtration through a 0.45 μm filter. Two different types of tests were conducted on the filters in order to determine the behavior of the filters with respect to leaching of organics, when subjected to different test conditions. The filtration test showed better results than the soak test and the polyethersulfone (PES) filter from manufacturer Filter Bio was the best option among all the tested filters.
