An enhanced electrokinetic remediation process for removal of arsenic, presented as As(V) form, from spiked soil has been investigated with groundwater (GW) and chemical reagents of cetylpyridinium chloride (CPC, a cationic surfactant), ethylenediaminetetraacetic acid (EDTA) and citric acid (CA) under potential gradient of 2.0-3.3V/cm for 5 days treatment. The removal efficiency of As(V) in EK-...

Electrokinetics (EK) is an emerging remediation technology for the in situ removal of heavy metals, volatile organic compounds, and radionuclides from soils and sediments. Naval Air Weapons Station Point Mugu, California will host an EK technology demonstration. The demonstration will consist of installing and operating an EK system, which is engineered to remove cadmium and chromium from forme...

Although electrokinetic effects are not new, only recently have they been investigated for possible use in energy conversion devices. We recently reported the electrokinetic generation of molecular hydrogen from rapidly flowing liquid water microjets [Duffin et al. J. Phys. Chem. C 2007, 111, 12031]. Here, we describe the use of liquid water microjets for direct conversion of electrokinetic ene...

Abstract This paper evaluates the remediation of soil spiked with lindane using a combined treatment consisting electrokinetic flushing (EKSF) air stripping to elucidate main processes occurring in when electric fields 0.75 V cm −1 and 1.50 are applied. The results demonstrate that is efficiently transported anodic cathodic wells fluids containing sodium dodecyl sulfate (SDS). Additionally, an ...

electrokinetic remediation is one of the most promising in situ or ex situ processes for decontamination of heavy metals, anions and polar organic compositions from the soil. in this study, we investigated the efficacy of this method in removing mercury from clayey soil (with kaolin to sand weight ratio of 2:1) and from gold mine tailing dam sediment and determined optimum removal conditions. t...

Polycyclic aromatic hydrocarbons (PAH) are toxic, mutagenic, and carcinogenic compounds. Removal of these compounds has a great importance for environment. Removal of PAHs from soil is difficult as these chemicals are persistent in the soil. In this research, bioremediation of soil contaminated by (PAH) using Bacillus subtilis DSMZ 3256 (B.subtilis) strains was studied. The effect of electrokin...

This work aims to shed light on the scale-up a combined electrokinetic soil flushing process (EKSF) with permeable reactive barriers (PRB) for treatment of spiked clopyralid. To do this, remediation tests at lab (3.45 L), bench (175 L) and pilot (1400 scales have been carried out. The PRB selected was made merged particles zero valent iron (ZVI) granular activated carbon (GAC). Results show tha...

In a rapidly evolving field such as Cognitive Rehabilitation Therapy (CRT), it is important for practitioners to be fully acquainted with the history and efficacy of their discipline. This review traces the development of Cognitive Rehabilitation over the past century and describes the status of CRT today. The authors describe various methods of Cognitive Remediation that are in current use alo...
