    Journal PapersJournal of Environmental Management , Volume 277 , 2021 January 1, {Pages 111422 }

    Abstract

    Electrokinetic (EK) by coupling surfactants is an enhanced promising remediation technology to eliminate hydrophobic organic contaminants (HOCs) from low-permeable soils. It is also applied to remediate kerosene-contaminated soils using anionic (SDS) and non-ionic (Tween 80) surfactants at different concentrations. There was negligible removal efficiency (40%) of kerosene during traditional EK without any enhancement technique. In the present study, the application of 0.005M and 0.01M SDS in EK-SDS-1 and EK-SDS-2 improved the removal efficiency to 50 and 55%, respectively towards the anode. Furthermore, the use of Tween 80 in EK-Tw80-1 and EK-Tw80-2 at 0.1 and 1% concentrations was able to raise kerosene removal gradually from 45% to 52% to

    Abstract

    A large amount of mine wastes is generated every year through mining and mineral processing operation. The management of mine tailings is an attractive topic for researchers from both environmental and economic aspects. Mine tailings have shown a capacity as a raw material for the construction industry or a substitution for previous materials to produce the cement. It is applied in some specific environments such as offshores or massive projects like large bridges and tunnels. However, the cement industry has caused a variety of environmental issues. The production of Portland cement on an industrial scale increases the greenhouse effects and generates acidic rains. It releases greenhouse gases by the generation of carbon dioxide. In recent

    Journal Papers , Volume 270 , 2020 September 15, {Pages 110881 }

    Abstract

    Over the past few decades, as demand for minerals and metals has increased, the amount and volume of wastes and tailings has also increased dramatically. The management and reuse of mineral wastes and tailings not only help protect the environment but also are properly associated with economic benefits. As a result, mineral processing wastes disposal and storage has become a global issue. Along with the use of cemented paste as a backfill in underground spaces, the use of mineral processing wastes in the construction industry or as a substitute for cement is one of the new approaches to mineral tailings management. It is worth noting that the cement industry is facing crucial environmental issues. Portland cement production in industries in

    Journal PapersEnvironmental Earth Sciences , Volume 79 , Issue 14, 2020 July , {Pages 18-Jan }

    Abstract

    The contaminated soil by mining activities could be transported through the erosive effect of wind. In this study, human health risk was assessed for exposure to heavy metals (Cu, Zn, Cd, Pb) present in surface soil of Irankouh zinc–lead mine, (the nearest mine to Isfahan, Iran) as one of the main dust storm sources. The effect of improper mining waste and tailings management in the Irankouh zinc–lead mine was not deeply investigated. Thus, 65 surface soil samples were collected (mining and residential area) and subjected into chemical analyses, then various assessment approaches were conducted on the obtained data. It was found that the mean concentrations of Zn (1035.2?mg?kg−1, SD = 563.7), Cd (2.53?mg?kg−1, SD = 1.1), an

    Journal PapersEnvironmental Pollution , Volume 266 , 2020 November 1, {Pages 115197 }

    Abstract

    Enhanced electrokinetic (EK) technique was employed to remediate Cr-contaminated soil using a permeable reactive barrier (PRB) and chelating agents. Synthesized nanomagnetic Fe3O4 was used as a reactive material in PRB. Moreover, EDTA and citric acid (CA) were used as chelating agents. Sequential extraction method (SEM) was employed to determine Cr-elimination mechanism during the EK process. The results revealed that EDTA (78% Cr removal) was more effective than CA (54% Cr removal) in eliminating Cr from the contaminated soil during the EK process. The application of PRB in combination with EDTA was able to reduce the Cr removal rate to 70 and 66% by locating PRB in the middle section and near the anode/cathode reservoir, respectively. The

    Behzad Eyvazi, Ahmad Jamshidi-Zanjani, Ahmad Khodadadi Darban
    Journal PapersEnvironmental Pollution , 2019 November 29, {Pages 113685 }

    Abstract

    The co-precipitation method was used to synthesize nano-magnetic adsorbent MnFe2O4 (nMFO), characterized through XRD, SEM, EDS, and BET techniques. The synthesized nMFO was used for hexavalent and trivalent chromium ions elimination from the aqueous phase. The optimum pH for the adsorption of Cr (VI) and Cr (III) was determined as 2 and 5, respectively. The chromium ions adsorption behavior was well interpreted through the pseudo-second order kinetics model. Furthermore, isotherm studies were conducted, and the obtained results indicated that Langmuir isotherm model could well justify the chromium ions adsorption process. Quick removal (less than 10?min) of both chromium ions and high removal efficiency were occurred using nMFO. The utmost

    Abstract

    Magnetite nanoparticles were produced from iron ore tailings and used to remove arsenate ions from water. The produced spherical nanoparticles were 25?3 nm in diameter and had ferromagnetic properties as discovered by XRD, FTIR, TEM, and VSM analyses. The kinetic and equilibrium of the arsenate (As 5+) adsorption by the magnetite nanoparticles was investigated in the presence of Cu 2+, Zn 2+ and Mn 2+ at pH= 5.5 (> pH PZC= 3.8). Due to the high stability of CuH 2 AsO 4+, the adsorption of arsenate was more noticeably affected by the copper ions compared to the rest of the metal ions. Biphasic first-order, pseudo-second-order, and Langmuir kinetic models were applied to simulate the arsenate adsorption. The maximum adsorption (9.72 mg/g) occ
