Sažetak
In this study, three groups of recovered papers, chosen with respect to paper type and printing technique, were treated in laboratory conditions by means of two different deinking methods. Recovered papers consisting of old newspapers (ONP) printed with coldset inks, supercalendered (SC) papers printed by means of rotogravure and lightweight coated (LWC) papers printed with heatset inks were subjected to separate flotation deinking and adsorption deinking treatments. After each conducted deinking treatment, filter pads were prepared from corresponding deinked pulps and subsequently analyzed on the content of saturated and aromatic mineral oil hydrocarbons (MOSH, MOAH) by GC/FID measurements. The aim of the study was to compare the effectiveness of two different deinking methods (adsorption deinking and flotation deinking) in the reduction of mineral oil hydrocarbons from defined recovered paper grades. For most tested samples adsorption deinking was found to be more successful in the reduction of mineral oils than the conventional flotation deinking method.
