Iranian Journal of Health, Safety and Environment, 2020 In the process of steel production by electric arc furnace (EAF), it is found that 10 to 20 kg of dust was emitted per every ton of produced steel. Concerning the pollution potential of emitted dust and its reuse ability, the present study was aimed to ...

Photocatalytic activity of electric-arc furnace flue dusts
Journal of Materials Research and Technology, 2020 Two electric-arc furnace flue dusts, a waste generated during the steel production process, were characterized and their photocatalytic activity was assessed. Chemical composition by X-ray fluorescence (XRF) analysis identified that both dusts were principally formed by iron, zinc and chromium oxides.

Experimental methods in chemical engineering: Atomic absorption spectrometry—AAS
The Canadian Journal of Chemical Engineering, EarlyView.Abstract Elements absorb electromagnetic radiation (light) of a specific wavelength in proportion to the number of atoms in its path. As the atoms absorb this light energy, electrons rise from the ground state to an excited state. In atomic absorption spectrometry (AAS), high temperatures produce clouds of atoms from the sample (atomization) and ...

Designing of Synergistic Waste Mixtures for Multiphase Reactive Smelting
Metals, 2016 Electric arc furnace (EAF) dust, together with a mill scale and coke were smelted in a laboratory electric arc furnace. These metallurgical wastes consist of a many different phases and elements, making the reaction process complex.
