Sažetak
In this study, recovered paper samples consisting of three print and substrate combinations, were prepared and treated in laboratory conditions by means of two different deinking methods. Recovered papers consisting of old newspapers (ONP) printed with coldset inks, rotogravure printed supercalendered (SC) papers and light weight coated (LWC) papers printed with heatset inks were submitted to a separate flotation deinking and adsorption deinking treatments. After each conducted deinking treatment, the filter pads were prepared from corresponding deinked pulps and were subsequently analyzed on the content of saturated and aromatic mineral oil hydrocarbons (MOSH, MOAH) by GC/FID measurements. Aim of the investigation was to compare the effectiveness of two different deinking methods (adsorption deinking and flotation deinking) in reduction of mineral oil hydrocarbons from the defined recovered paper grades. For most of the tested samples adsorption deinking was found to be more successful in reduction of mineral oils than the conventional flotation deinking method. Through adsorption deinking over 60% up to 80% of mineral oils were removed from recovered papers. It was also found that adsorption deinking was quite effective in reduction of amounts of mineral oils even in cases when it was not efficient enough in removing printing ink particles from recovered paper pulp.
