In recent years, the development of suitable technologies for remediation environmental contaminations has attracted considerable attention. Among these, electrochemical approaches have gained prominence thanks to many possible applications and their proven effectiveness. This is particularly evident in case inorganic/ionic contaminants, which are not subject natural attenuation (biological deg...

The remediation of petroleum hydrocarbons (TPH) in a contaminated soil by electrokinetic (EK) treatment was studied the laboratory. effects applying constant electrical current on pH, moisture content, conductivity (EC), temperature, and concentrations three fractions TPH (C10–C16, C17–C34 C35–C40) were investigated. experiment run for seven days samples collected at end 7 day period analysis p...

Electrokinetic soil remediation is often impeded by the aggregation of small particles, within soil, during procedure. The porous network subsequently clogged which results in immediate process termination. In order to overcome this limitation, feasibility electrokinetic coupled simultaneously with two enhancing techniques was investigated: modified periodic polarity reversal and catholyte pH c...

Recently developed man-made structures have caused environmental pollutions, and unfortunately, in spite of the deteriorating affairs and repeated warnings by scientists and experts, the degree of contamination is increasing considerably. One of the natural sources undergoing changes is the coasts. It is mainly due to human activities which have led to a change in the quality and quantity of se...

PURPOSE In this study, a novel and ecological alternative have been developed to treat soils contaminated with hexavalent chromium coupling two well-known systems: electrokinetic remediation and permeable reactive biobarriers. The electric field promotes the electromigration of the hexavalent chromium oxyanions towards the anode. The biobarriers were placed before the anode electrode, in order ...

The influence of direct current electric fields on the possible electrokinetic delivery of nano-iron slurry in clay for the purpose of fast and effective remediation of soil contaminants has been tested. Nano-iron can be introduced to soil hydraulically in slurry form, but in tight clay soil, delivery of a uniform distribution of the slurry may be difficult to achieve for effective remediation....

This work investigates the influence of soil type on electrodialytic remediation (EDR) of lead (Pb). In electrokinetic soil remediation, it is well known that pH is a key factor and that carbonate influences remediation efficiency negatively. This work provides results from laboratory-scale EDR experiments with ten representative industrially Pb-contaminated surface soils. Results indicate that...

Most food waste is incinerated and reclaimed in Korea. Due to the development of industry, soil groundwater pollution are serious. The purpose this study was recycled materials eco-friendly remediation methods prevent secondary after remediation. In study, ash filled a permeable reactive barrier (PRB) used as heavy metal adsorption material. situ electrokinetic techniques (EK) acetic acid were ...
