“…Colonization of GAC and zeolites by petroleum hydrocarbon degraders presents the potential for bioremediation within PRBs (Kubota et al 2008;Yeh et al 2010;Vignola, Bagatin, D'Aurisb, Flegoc et al 2011;Vignola, Bagatin, D'Aurisb, Massara et al 2011;Gibert et al 2013), although this is yet to be trialled in the Antarctic or Arctic. Xin et al (2013) investigated the coupling of bioaugmentation and PRBs by examining the response of Mycobacterium sp.…”

“…Granular activated carbon (GAC) has been shown to be only slightly effective in treating water containing very soluble compounds, such as oxygenated organics, or low molecular weight compounds, such as DCE and vinyl chloride (VC) [5]. Recently Vignola et al [6] have demonstrated that hydrophobic zeolites are able to effectively adsorb molecules against which ZVI or GAC are totally ineffective. In particular, ZSM-5 zeolite turned out to be suitable for mono-aromatic molecules, such as BTEX (benzene, toluene, ethylbenzene and xylene) and halogen-benzene derivatives [6].…”

We investigated the 1,2-dichloroethane (DCE) adsorption process into an organophilic zeolite mordenite. A combined diffractometric, thermogravimetric and gas chromatographic approach enabled to obtain clear evidence of DCE adsorption in mordenite channels as well as to pinpoint the exact location of the organic species found in the structure. Rietveld refinement revealed the incorporation of 2.5 DCE molecules and approximately 4 water molecules within the mordenite channel system, in very good agreement with the weight loss given by TG analysis and the saturation capacity determined by the adsorption isotherm. This relevant incorporation of DCE molecules caused a remarkable increase in the dimension of the 12-ring, when compared to the parent zeolite. The distances between the oxygen atoms of the water molecules from the chlorine atoms of the organic molecule (W-Cl1 = 2.34 Å, W-Cl2 = 2.53 Å) suggest that different DCE molecules could be connected by means of hydrogen bonds through water, to form a DCE and water molecule complex. The isotherm adsorption model for organic compounds from an aqueous dilute solution was selected based on the results of the structural investigation. Graphical abstract 2 HighlightsEvidences of DCE adsorption into mordenite are reported. 2.5 DCE and 4 water molecules were adsorbed into the mordenite framework. The adsorption of DCE into mordenite caused distortions of the 12-ring channels.

“…However, the high costs of reactive materials make the system unaffordable to developing countries. (Liu et al, 2013;Obiri-Nyarko et al, 2014), zeolite (Kovalick and Kngscott, 1995;Vignola et al, 2011), activated carbon (Natale et al, 2007), Peat (Kao and Yang, 2000). Among these materials, ZVI is widely used in PRBs to clean contaminated groundwater and surface water (Obiri-Nyarko et al, 2014).…”

Recently, groundwater sources are being polluted by various activities such as agriculture, livestock, decentralized wastewater treatment systems and acid rain. Groundwater can also be polluted by landfill leachate, sewage, mine tailings, non-engineered deep well disposal of liquid waste and seepage from industrial waste lagoons. There are many studies reported contaminated groundwater remediation using Permeable Reactive Barrier systems (PRBs) and many countries happen to use this system to eliminate groundwater contaminants. This study reports the outcomes of the batch and the column test experiments conducted to evaluate the removal efficiency of four heavy metals: Cd(II), Cu(II), Fe(II) and Pb(II) using five locally available reactive materials (in Sri Lanka) with grain sizes less than or equal to 2.0 mm: Red Soil (RS), Laterite Soil (LS), Bangadeniya Soil (BS), Burnt Clay Tile (BCT) and Coconut Shell Biochar (CSB) as PRB materials. Seven columns (A-G) were filled with the reactive material of CSB (column E) and reactive material mixtures; RS + CSB (column A), LS + CSB (column B), BCT+CSB (column C), BS + CSB (column F), RS + LS (column G), with a weight ratio of 50:50 and RS + BCT + CSB (column D) with a weight ratio of 100/3:100/3:100/3. The results showed that the reactive materials filled in column A, B, D, F and G removed the metal concentrations, with a removal efficiency of over 90%, except Cd in the column with BCT + CSB mixture. Considering both the removal efficiency and the hydraulic conductivity of the columns, materials in column A, B, D and F are more effective than the others as PRB adsorbents for heavy metal remediation, while columns C and E have lower removal efficiency.
