Abstract
Cilj ovog rada bio je odrediti maseni udio traženih analita, bisfenola A, benzofenona i 4,4'-(4-metilpentan-2,2-diil)difenola u uzorcima termokromnih boja te u uzorcima otisaka termokromne boje na papir kao i u uzorcima otisaka termokromne boje na papiru nakon izlaganja uvjetima anaerobne razgradnje u tlu. U ovom radu analizirani su uzorci četiri termokromne boje: Green curing flexo 25C UV, Red 75/80 irreversible, Magenta MB 60 i Blue-2 W50-0. Od navedenih uzoraka određeno je da samo boja Green curing flexo 25C UV sadrži traženi analit 4,4'-(4-metilpentan-2,2-diil)difenol u masenom udjelu od 0,1 % te također sadrži 0,7 % bisfenola A. U ostalim uzorcima nisu pronađeni traženi analiti. Potom je slijedila analiza uzorka Offset green to yellow otisnutog na više vrsta papira, bezdrvni premazani (BP), bezdrvni nepremazani (BN), te 33 % reciklirani (R33). Ovi uzorci bili su izloženi anaerobnoj razgradnji u tlu tako da je za svaku vrstu papira provedena analiza za sljedeći broj dana trajanja anaerobne razgradnje u tlu: 14, 32, 50 te 80 dana. Ovom analizom utvrđeno je da udio analita 4,4'-(4-metilpentan-2,2-diil)difenola raste u opisanim uvjetima anaerobne razgradnje u tlu.
Abstract (english)
The aim of this work was to determine concentration of selected analytes which are bisphenol A, benzophenone and 4,4'-(4-methylpentane-2,2-diyl)diphenol in thermochromic printing inks and in their prints on papers which have also been exposed to anaerobic decomposition in soil. In this analysis four samples of thermochromic printing ink have been analyzed: Green curing flexo 25C UV, Red 75/80 irreversible, Magenta MB 60 and Blue-2 W50-0. From the analysis of these samples it was found that only sample Green curing flexo 25C UV has selected analytes: 4,4'-(4-methylpentane-2,2-diyl)diphenol in mass fraction of 0,1 % and 0,7 % of bisphenol A. Other samples were found to be free from selected analytes. Then the analysis of thermochromic prints on paper using Offset green to yellow ink followed. The prints were made on various types of papers: wood-free coated (BP), wood-free uncoated (BN) and 33 % recycled (R33). Samples of these printed papers were subjected to anaerobic decomposition in soil, which was terminated at different time periods: 14, 32, 50 and 80 days. In these analyses, it was found that concentration of analyte 4,4'-(4-methylpentane-2,2-diyl)diphenol rises in described conditions of anaerobic decomposition in soil.
