Removal of hexavalent chromium of contaminated soil by coupling electrokinetic remediation and permeable reactive biobarriers.
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 ...
متن کاملinvestigation of hexavalent chromium cr (vi) removal from contaminated clayey soil by simultaneous combination of electro kinetics and nano zero-valent iron as a permeable reactive barrier
recently, a variety of soils contaminated with heavy metals e.g. cr (vi), have been found in industrial sites. such soil contamination is widely distributed in the world and has now become a serious issue for environment. hexavalent chromium, cr (vi), which is known to be carcinogenic and mutagenic to living organisms, has been utilized for leather tanning, electroplating and in other industrie...
متن کاملElectrokinetic Remediation of Uranium Contaminated Soil by Ion Exchange Membranes
Abstract—The contamination of significant quantities of soils and sediments with uranium and other actinide elements as a result of nuclear activity poses many environmental risks. The electrokinetic process is one of the most promising remediation techniques for sludge, sediment, and saturated or unsaturated soils contaminated with heavy metals and radionuclides. However, secondary waste is a ...
متن کاملeffect of alternative electrolytes on enhanced electrokinetic remediation of hexavalent chromium in clayey soil
hexavalent chromium is mobile and hazardous in the environment. electrokinetic remediationof chromium (iv)-contaminated soils is intended either to remove or to reduce cr (vi) to cr (iii). this studyexamines the effectiveness of utilizing edta and acetic acid solutions as alternative electrolytes in theelectrokinetic (ek) process, with coupled nano-scale zero-valent iron (nzvi) as a barrier for...
