“…The capacity for dye removal by BFS was demonstrated in a batch experiment. The pH of the BFS samples was determined by dispersing the BFS at 1:5 (w/v) with deionised water followed by shaking for 24 h. Different variables were considered to determine the optimum conditions to remove the dye from wastewater, such as the adsorbent dose, contact time and adsorbate dose in optimisation test design adopted from Gao et al [5]. All experiments were conducted at room temperature.…”

“…In a previous study by Wang et al [4], the contact time of up to 2 h was used to remove dyes of active red X-3B and CTMAB by BFS. Most of the dyes were absorbed in the first 40 min and the adsorption reached equilibrium at 1 h. In another study by Gao et al [5] different BFS materials of BFS micropowder (BFSMP), BFS acidified solid (BFSAS) and BFS acid-alkali precipitate (BFSAP) were compared for their MO adsorption performance. The contact time of 25 min was determined as the equilibrium time for adsorption and the removal rate was 99.8%, 85% and 4% for BFSAP, BFSAS and BFSMP, respectively at conditions of the initial MO concentration of 25 mg/L, pH 11, temperature of 25 °C and adsorbents dose of 0.1 g in 50 mL liquid.…”

“…BFS consists of the inorganic nonferrous fractions of the raw materials used in ironmaking (iron ore, coal/coke and fluxes, including limestone), that remain after the extraction of the iron from the ore [3,4]. Calcium and silica oxides are the main chemical components in BFS along with other oxides, such as Al2O3 and MgO, and other metallic elements, such as Fe, Ti and Mn [1,5,6]. The chemical composition of BFS varies with the grade of iron ore and the fluxes used in smelting [4], while its structural phase is influenced by the slag cooling rate [7].…”

“…On the other hand, the dye removal rate increased with an increase in contact time, temperature and initial dye concentration [23]. In another study, BFS was treated and synthesised into three materials comprising BFS micro powder, BFS acidified solid and BFS acid-alkali precipitate to investigate their efficiency for methyl orange (MO) dye removal [5]. Results indicated that the BFS acid-alkali precipitate has better removal ability and when the pH was in the range of 3-13, the removal efficiency of the solution with a dye concentration of 25 mg/L reached 99.97% in 25 min at room temperature.…”

Blast Furnace Slag (BFS) is a by-product of the iron ore processing industry with potential to be used in different industrial applications. In this research, BFS was used to examine its ability for dye removal from wastewater. The efficiency of two types of BFS samples for removal of cationic methylene blue (MB) and acidic methyl orange (MO) dyes was investigated and results found that the optimal conditions for treatment of wastewater were 80 g/L of adsorbent dose and 1 h of treatment time for both dyes. BFS was found to be more effective for removal of the acidic MO dye than the cationic MB dye. Under shorter residence times, the results showed reverse trends with BFS samples removing higher concentrations of MB than MO. The BFS chemistry had additional impacts on the efficiency of dye removal. Higher basicity of BFS had lower dye removal ability for adsorption of acidic dye when applied at smaller concentrations, while for cationic dye when applied at higher concentrations. The results showed that BFS has potential role for pre-treatment of industrial wastewater contaminated with dyes and may contribute to reduced use of more expensive adsorbents, such as activated carbons.

“…It was predicted that the porous structure of the slag would absorb the contaminants and free lime in the slag could react with the contaminants (Jha et al 2004(Jha et al , 2008Lu et al 2008). In addition, inertial impaction, diffusion, interception, size exclusion, and electrostatic interaction could also be the reason for contaminant removal in slag filtration (Gao et al 2017;Zhou et al 2016). It was reported that ironmaking slag was capable of removal of hydrogen sulfide which was attributed to the oxidation and acid-base reaction (Xie et al 2017).…”

Along with iron and steel production, large amount of slag is generated. Proper management on the iron-and steelmaking slag is highly demanded due to the high cost of direct disposal of the slag to landfill, which is the most adopted management approach. In this article, the potential application of iron-and steelmaking slag has been reviewed, which included the slag utilization in construction as cement and sand, in water, soil, and gas treatment, as well as in value material recovery. In addition, the challenge and required effort to be made in iron-and steelmaking slag management have been discussed.

Blast furnace slag functionalized with sulfamic acid (zwitterion) shows an extraordinary potential for the removal of biogenic amines from spiked water and real wastewater samples. The functionalized slag is characterized using scanning electron microscopy‐energy dispersive spectroscopy (SEM/EDS), Fourier transform infrared spectroscopy (FTIR), and acid site density test. Its performance toward the removal of selected biogenic amines (putrescine, tyramine, and 2‐phenylethylamine) is evaluated at different experimental conditions that include pH, contact time, adsorbent dosage, and initial concentration. The central composite experimental design is employed in investigating the effect of these individual factors and their interactions. The adsorption experiment results fit both the Langmuir isotherm model and pseudo‐second‐order kinetic model based on the computed high coefficient of determination (R2) values. Maximum adsorption capacity values of 80.64 mg g−1 for 2‐phenylethylamine, 12.5 mg g−1 for putrescine, and 64.52 mg g−1 for tyramine are estimated from the Langmuir isotherm model. Hydrogen bonding interaction between the S═O groups of the functionalized slag and protonated amino groups of biogenic amines is speculated as the possible mechanism of adsorption. The prepared functionalized slag also exhibits good adsorptive removal of biogenic amines in a date palm fruit processing industrial wastewater sample.
