AB  - Pristine electric arc furnace slag (EAFS) as well as EAFS modified by alkali activation i.e. alkali activated slag (AAS) have found a novel application as adsorbents used in Cu2+ removal from sulfate solutions. The adsorption tests were carried in batch conditions and results have shown that alkali activation of EAFS enhances the Cu2+ adsorption. The adsorption process was found to follow a pseudo second-order kinetic model and occurs via formation of posnjakite (Cu4(SO4)(OH)6·H2O) on the surface of both, EAFS and AAS. Enhanced adsorption properties of AAS, compared to EAFS, are attributed to a more porous structure, larger specific surface area and an increased number of surface groups involved in the binding of Cu2+.

AB  - Electric arc furnace slag (EAFS) and electric arc furnace dust (EAFD) are the waste materials generated during the iron and steel scrap remelting in electric arc furnace. EAFS is non-hazardous material which has found its application in different field of civil engineering. On the other hand, EAFD is classified as hazardous matreials due to the presence of heavy metals (Zn, Pb, Cu Cr and Cd) and their potential leaching into environment. Stabilization/solidification (S/S) of toxic waste is a widely investigated as simply method for production of stable product. Cement binder was mainly used for this purpose but important shift in the use of different waste materials as a cement replacement was observed. The aim of this study was to investigate the possibility of S/S of heavy metals from EAFD using the alkali activated binders based on EAFS. The alkali activated slag with a different content of EAFS was synthesised and characterized using the SEM/EDS, XRDP, FTIR. The binding of Zn into the reaction product of slag alkali activation was founded. The immobilization efficacy was evaluated using TCLP Method No. 1311 (USEPA) and EN 12457-2 (EULFD) leaching tests.

AB  - The removal of heavy metals from wastewaters is presently a global imperative primarily due to their well-known toxic nature and detrimental effects on the environment, and more importantly, on human health. Currently, special attention is paid to the use of novel slag based materials – alkali activated slag (AAS) as potential novel adsorbents. Our previous studies have shown that electric arc furnace slag (EAFS) can be successfully used as a precursor for the production of AAS. Generally, alkaline activation involves a chemical reaction between solid aluminosilicate materials and a highly alkaline activator. The alkali activation mechanism of slag involves the dissolution of slag in a highly alkaline, which is followed by the condensation and hardening processes. Dependent on the pH and type of alkaline activator, calcium (alumina) silicate hydrate or C–(A)–S–H gel has been identified as a reaction product of slag alkali activation. The objective of this research was to investigate the removal of Cu2+ from aquatic solution using alkali activated slag (AAS) obtained by alkaline activation of EAFS.

AB  - This study aims to understand the kinetic, thermodynamic and mechanism of Cu2+ adsorption onto unmodified electric arc furnace slag (EAFS) and alkali modified EAFS. The adsorption process was investigated via a batch reactor system. The modified EAFS sample has been prepared by reacting an EAFS powder with an aqueous alkali silicate solution. The both samples were characterized by SEM, XRD, FTIR and porosimetric measurements. The results have shown that alkali activation of EAFS favour adsorption process. The adsorption reaction on both adsorbents was found to be pseudo second order. Thermodynamic investigations have shown that adsorption process is spontaneous and endothermic. Mechanism of adsorption was investigated using the intraparticle diffusion and Boyd model which suggested that the both, film diffusion and diffusion within the pores of adsorbent controls the intraparticle diffusion of Cu2+ onto and EAFS and modified EAFS and was mainly due to external mass transport. Besides, FTIR spectroscopy determined the surface functional groups of the EAFS and modified EAFS which participate in Cu2+ bonding.
