Abstract
U ovom radu istraživana je mogućnost uklanjanja Cu (II) iona iz vodene otopine koristeći metalurški otpad. Povećana koncentracija Cu (II) iona u vodi može imati negativne posljedice na čovjeka, životinje i biljke te se Cu (II) ioni moraju ukloniti iz otpadne vode prije puštanja u odvod ili prirodne recipijente. U ovom radu korištena je otpadna čelična sačma kao adsorbens za uklanjanje Cu (II) iona iz vodene otopine. Eksperimentalni podaci opisani su kinetičkim modelima reakcije pseudo prvog i pseudo drugog reda, kao i Freundlichovom i Langmuirovom izotermom. Dobiveni rezultati pokazali su da se kinetika adsorpcije Cu (II) iona na otpadnoj čeličnoj sačmi odvija prema kinetičkom modelu pseudo drugog reda. Adsorpcijski proces sustava otpadna čelična sačma/Cu (II) ioni može se odvijati i prema Freundlichovom, kao i prema Langmuirovom modelu. Izglednije je da se adsorpcija odvija prema Freundlichovom modelu, odnosno da je fizikalne prirode.
Abstract (english)
The possibility of removal of Cu (II) ions from aqueous solution using metallurgical waste was researched in this paper. The increased concentration of Cu (II) ions in the water can have negative effects on humans, animals and plants. Therefore, they must be removed from waste water before discharge into drains or natural recipients. In this paper, waste steel shot was used as the adsorbent for removal of Cu (II) ions from an aqueous solution. The experimental data are described using the kinetic models of the reaction of the pseudo first and pseudo second order, as well as Freundilich and Langmuir isotherm. Obtained results showed that the kinetics of adsorption of Cu (II) ions on the waste steel shot takes place according to the kinetic model of the pseudo second order. Adsorption of Cu (II) ions on the waste steel shot can take place according to the Freundilich and Langmuir model. It seems more likely that the adsorption takes place according to Freundilich model, which indicates the physical nature of the process.
