Adsorption and Desorption Study of Locally Available BOF Sludge to Remove Metal Ions from Aqueous Solutions

Popis výsledku v původním jazyce

Coarse BOF sludge is a waste originating from steelmaking production. The major phaseof this waste is zinc ferrite. BOF sludge for this study was obtained from the metallurgical industryfrom a process of gas treatment in an oxygen converter. The sorption of cobalt, manganese and nickelions was investigated in the sample of the deposited sludge in a batch of experiments. The sorptionprocess was evaluated using three types of isotherm models. The sludge sample was alkaline andconsisted primarily of X-ray amorphous compounds and crystalline Fe oxides. The adsorptionprocess showed that a high removal efficiency was achieved at a lower initial concentration of metalions. Moreover, the equilibrium of the sorption process was achieved after 72 hours. Subsequently,the desorption of these adsorbed ions was investigated. The results of this study indicate that theapplication of metallurgical waste as a sorbent is highly effective for the treatment of wastewater.
