Abstract (croatian)

Metalurški otpad ima velik potencijal za uporabu kao adsorbens za uklanjanje teških metala iz otpadnih voda, ističući se kao mogući jeftini adsorbens. U ovom članku prikazano je adsorpcijsko ponašanje Zn(II) iona na dva kruta metalna otpadna materijala – otpadnoj kalupnoj mješavini (OKM) i otpadnoj anodnoj prašini (AP). Dobiveni rezultati pokazali su da se oba otpadna materijala mogu upotrebljavati kao potencijalni adsorbensi. Anodna prašina ima bolja adsorpcijska svojstva. Ravnotežni podatci za adsorpciju Zn(II) na otpadnim metalurškim materijalima ispitani su Freundlichovim i Langmuirovim izotermnim modelima. Utvrđeno je da je Langmuirov model prikladniji te da se adsorpcija odvija kao kemisorpcija.

Abstract (english)

Metallurgical waste has great potential for use as an adsorbent for the removal of heavy metals from wastewater, standing out as possible low-cost adsorbents. This article presents the adsorption behaviour of Zn(II) ions on two solid metal waste materials – waste mould sand (WMS) and anode dust (AD). The obtained results showed that both waste materials could be used as potential adsorbents. Anode dust has better adsorption properties. The equilibrium data for the adsorption of Zn(II) on waste metallurgical materials were examined by Langmuir and Freundlich’s adsorption isotherm models. It was found that the Langmuir model is more appropriate, and that adsorption takes place as chemisorption.
