Ligand-enhanced electrokinetic remediation of metal-contaminated marine sediments with high acid buffering capacity.

The suitability of electrokinetic remediation for removing heavy metals from dredged marine sediments with high acid buffering capacity was investigated. Laboratory-scale electrokinetic remediation experiments were carried out by applying two different voltage gradients to the sediment (0.5 and 0.8 V/cm) while circulating water or two different chelating agents at the electrode compartments. Ta...

Enhanced electrokinetic remediation of cadmium contaminated soils by chelating agents

Electrokinetic soil remediation by electroosmosis and ionic migration is restricted to soluble substances. At a higher pH, the soil particles sorb more heavy metals than at a lower pH and the precipitation reactions of heavy metals are promoted. Both mechanisms make heavy metals immobile, rendering cleanup more difficult and electrokinetic extraction inefficient. In this study, the effectivenes...

Electrokinetic Remediation of Mercury-contaminated Soils

A series of batch tests were conducted to investigate the relative desorption potential of mercury from kaolin and glacial till soils under the effect of three extractant agents, namely, KI, NaEDTA and NaCl (all of them with a concentration of 0.1 M). These tests were conducted under different pH conditions (within a pH range between 2 and 12). Also batch tests using deionized water were perfor...

Electrokinetic remediation of oil-contaminated soils.

This investigation was undertaken to determine the factors influencing electrokinetic remediation of soils from petroleum pollutants. The remediation method was applied in two versions: (i) static and (ii) flowing, when a sample was washed with leaching solution. It was found that all the soils studied can be purified using this technique. It was also observed that the mineral and grain-size co...

Reducing Agents Enhanced Electrokinetic Soil Remediation (EKSR) for Heavy Metal Contaminated Soil

Reducing agents-Enhanced electrokinetic Soil Remediation (EKSR) was performed for the removal of chromium (Cr), cobalt (Co) and nickel (Ni) from contaminated soil. The reducing agents oxalic acid and ascorbic acid were investigated under constant voltage gradient (2.0 V/cm), current changes, pH, redox potential, concentration changes and removal performance of Heavy Metals (HMs). The result...
