Electrokinetic enhancement removal of heavy metals from industrial wastewater sludge.
An enhanced electrokinetic process for removal of metals (Cr, Cu, Fe, Ni, Pb, Zn) from an industrial wastewater sludge was performed. The electrokinetic experiments were conducted under a constant potential gradient (1.25 V cm(-1)) with processing fluids of tap water (TW), sodium dodecylsulfate (SDS) and citric acid (CA) for 5 days. Results showed that metal removal efficiency of heavy metals f...
متن کاملRemoval of Heavy Metals from Aqueous Solution by Mordenite Nanocrystals
This study examined the ability of the synthetic mordenite nanocrystal to remove Tl(III) and As(III) from an aqueous solution. The determination of the concentration changes of H+ and OH- quantities in the acidic (pH 3) and alkali (pH 9) treated mordenite nanocrystals were done by the potentiometric titration curves. The maximum uptake capacities (Qmax) of these metal ions using the mordenite i...
متن کاملRemoval or Reducing Heavy Metal (lead) from Soil by Electrokinetic Process
The electrokinetic process is an emerging technology for in situ soil contamination, in which chemical species, both ionic and nonionic are transported to an electrode in soil. These products are subsequently removed from the ground via collection systems engineered for each specific application. Electro kinetics refers to movement of water, ions and charged particles relative to one another un...
متن کاملCoupled Electrokinetics-Adsorption Technique for Simultaneous Removal of Heavy Metals and Organics from Saline-Sodic Soil
In situ remediation technologies for contaminated soils are faced with significant technical challenges when the contaminated soil has low permeability. Popular traditional technologies are rendered ineffective due to the difficulty encountered in accessing the contaminants as well as when employed in settings where the soil contains mixed contaminants such as petroleum hydrocarbons, heavy meta...
متن کاملTwo-dimensional model for soil electrokinetic remediation of heavy metals. Application to a copper spiked kaolin.
A two-dimensional numerical model has been developed to simulate the electrokinetic remediation of soils contaminated with heavy metals and has been validated using laboratory experiments performed with a copper spiked kaolin. The model divides the soil into compartments in a Cartesian grid and a non-conductivity barrier encloses the considered area. Basically, it consists in two main parts cle...
