“…In fact, the decrease was directly proportional to time. When Jean-Soro et al [45] observed leaching of Ni and Cr with EDTA and citric acid, more Cr was leached with citric acid than with EDTA.…”

Metal contamination is a matter of serious concern throughout industrial areas of the world. Most industrially polluted regions are laden with heavy metals and among them Cu, Cd, and Cr are the most important especially in tannery-and textile-polluted areas. The process of phytoextraction can be enhanced with biological or chemical assistants. Among the chelating agents, EDTA has been the most effective in hastening the process of phytoextraction [1, 2]. A few plant species with high biomass show the capacity to translocate high amounts of heavy metals from roots to shoots [3]. Zhivotovsky et al. [4] have reported that complexation of metals with EDTA reduces their bioaccumulation in roots and thus enhances translocation of metals to aerial parts of plants. Nevertheless, Barrutia et al. [5] argued that

“…The effectiveness of chelators is a function of concentrations of chelators, types and concentrations of metals, the stability constants of complex, pH, etc. (Jones 1998;Jean-Soro et al 2012;Perez-Esteban et al 2013). According to results in Table 3, most of the CA was complexed with Fe and Mn, but not Al.…”

Acid mine drainage (AMD) poses serious environmental problems. This study assessed the effect of plant age, rhizosphere bacteria, and citric acid (CA) on the metal plaque formation and metal uptake in Phragmites australis cultured in a synthetic AMD solution. Iron-oxidizing bacteria (Fe(II)OB) enhanced the formation of Fe plaque, which slightly decreased Fe and Mn uptake. CA reduced the growth of Fe(II)OB and formation of Fe plaque, thereby increasing the Fe and Mn accumulations in reeds. Adult reeds had developed more Fe plaque on the root surface than seedlings. However, the adult reeds still accumulated higher concentrations of metals due to their higher tolerance to toxic environments and bigger biomass. With 9.02 g/L CA, adult reeds accumulated 0.51 ± 0.00 mg Mn, 109.38±1.37 mg Fe, and 1.77±0.04 mg Al. More investigation may be needed to further study the effect of CA when applied to AMD-contaminated field.

International audienceTreatment of industrial wastewaters by electrocoagulation is very efficient to remove numerous types of pollutant (organic, mineral, colored, metal). However, few researches are devoted to the elimination of metals contained in the generated sludge. The objective of this paper was to study the possible simultaneous removal of aluminum (issued from the electrodes) and chromium (initially present in the effluent) contained in the sludge by electrochemical migration. Electrocoagulation treatment of textile industrial wastewater in which chromium has been added was carried out using aluminum electrodes. Turbidity, COD, and TOC could be efficiently removed with abatement yields, respectively, at 97, 93, and 90%. For chromium, only 62% of the initial amount was eliminated by applying the highest current with a long operating time. The generated sludge contained high amounts of Cr and Al (749 and 1,260 mg/kg of dry sludge), far above the maximum level allowed by legislation. The possibility of removing these pollutants from the resulting sludge using electrokinetic technique was investigated. Acetic acid at 1 or 3 M and citric acid at 3 and 6 M were used as catholyte solutions to enhance the removal of aluminum and chromium (III). Best results for aluminum removal were obtained using 3 M acetic acid: up to 82% of the initial Al was recovered in the cathode chamber, whereas citric acid was more effective in chromium removal: up to 79% was transported to the cathode chamber with 6 M citric acid. Specific energy consumption is also discussed
