Ovaj rad proučava adsorpciju Cr(VI) iona na ugljičnoj anodnoj prašini koja predstavlja otpadni materija nastao pri proizvodnji aluminija. Šaržnim postupkom ispitana je adsorpcija Cr(VI) iona u području koncentracija 100-500 mg/l te utvrđeno vrijeme uspostavljanja adsorpcijske ravnoteže. Nakon 60 minuta došlo je do uspostavljanja ravnoteže. Ravnotežni podaci analizirani su Langmuirovom i Freundlichovom izotermom. Određeni su karakteristični parametri. Eksperimentalni podaci bolje se slažu s Langmuirovom izotermom nego s Freundlichovom. Rezultati pokazuju da se ugljična anodna prašina može koristiti kao jeftini adsorbens za uklanjanje Cr(VI) iona iz vodenih otopina..; This study investigated the adsorption of Cr (VI) ions on carbon anode dust, which is industrial waste material from aluminium production. The adsorption of Cr (VI) ions in the concentration of 100-500 mg/l was studied by means of the batch process and the time of establishment of adsorption equilibrium was determined.A contact time of 60 min was required to reach the equilibrium. The equilibrium data were analyzed using the Langmuir and Freundlich isotherms. The characteristic parameters for each isotherm were determined. Experimental data better agree with the Langmuir than with the Freundlich isotherm.. The results show that carbon anode dust can be used as a low cost adsorbent to remove Cr (VI) ions from water solutions.
