Abstract

U ovom radu su istraživana adsorpcijska svojstva metalurškog otpada. Istraživanja su provedena na otpadu iz proizvodnje čelika-elektropećna troska, otpadu iz ljevaonice-otpadna kalupna mješavina i otpadu iz proizvodnje aluminija-anodna prašina. Provedena je kemijska i mineraloška analiza kao i određivanje specifične površine, volumena i promjera pora, te određivanje funkcionalnih grupa ispitivanih uzoraka. Radi potvrde dobivenih rezultata koji se odnose na adsorpcijska svojstava ispitivanih otpada napravljeni su dodatni adsorpcijski eksperimenti u realnim uvjetima. Adsorpcijska svojstva ispitivanih uzoraka uspoređena su s adsorpcijskim svojstvima aktivnog ugljena, najboljeg komercijalnog adsorbensa. Unatoč različitim sastavima i strukturama ispitivanih uzoraka, dobiveni rezultati su pokazali da se svi ispitivani otpadni materijali mogu koristiti kao alternativni jeftini adsorbensi.

Abstract (english)

In this paper, the adsorption properties of metallurgical waste were investigated. The research was carried out on waste from the production of steel – electric arc furnace slag, waste from the foundry - waste mould mixture and waste from the production of aluminium - anode dust. Chemical and mineralogical analysis was performed, as well as the determination of the specific surface area, volume and diameter of pores, and the determination of the functional groups of the tested samples. In order to confirm the obtained results related to the adsorption properties of the tested wastes, additional adsorption experiments were performed in real conditions. The adsorption properties of the tested samples were compared with the adsorption properties of activated carbon, the best commercial adsorbent. Despite the different compositions and structures of tested samples, the obtained results showed that all tested waste materials can be used as alternative cheap adsorbents.
