Electrokinetic remediation has been tested to remove lead from an Algerian contaminated soil sited near a battery plant. High level of lead content (4432 ± 275μg/g) mainly causes a pollution of the zone area which is sited nearby an agricultural land. A sequential chemical extraction procedure has shown that up to 71% of the total lead is found bounded to the mineral surfaces symbolised by Fe –...

Hydroxyapatite nanoparticles (nHAP) have been widely used to remediate soil and wastewater contaminated with metals and radionuclides. However, our understanding of nHAP transport and fate is limited in natural environments that exhibit significant variability in solid and solution chemistry. The transport and retention kinetics of Alizarin red S (ARS)-labeled nHAP were investigated in water-sa...

Rare earth elements (REE) are essential for sustainable energies such as solar and wind power, with rising demand due to the ambitious goal a circular society. REE currently mined from virgin ores while REE-rich contaminated soil is left untreated in environment. Soil remediation strategies needed that concomitantly cleanup harvest metals contribute process economy. In this review we aim (i) de...

A mathematical model of an acoustoelectric transducer based on the use electrokinetic phenomenon flow potential is proposed. It shown theoretically that increases in proportion to strength constant electric pumping field, which confirmed experimentally. The described converter has variable sensitivity. Rather large values sensitivity microphone have been obtained results work can be used design...

effect of different concentrations of ammonium chloride (ncl) and ammonium nitrate (nn)and surfactants such as tween-80, hpcd and rhamnolipids on the bioremediation of pahs and ocps wasinvestigated. the results showed that the best optimum concentration of ncl and nn was 50 g·kg-1, and thepahs degradation rate during 60 days of remediation was enhanced to 64.6% and 62.8% for ncl and nn,respecti...

We present a theory to investigate electrokinetic behavior, namely, electrorotation and dielectrophoresis under alternating current (ac) applied fields for a pair of touching inhomogeneous colloidal particles and biological cells. These inhomogeneous particles are treated as graded ones with physically motivated model dielectric and conductivity profiles. The mutual polarization interaction bet...

Active manipulation of cells, such as trapping, focusing, and isolation, is essential for various bioanalytical applications. Herein, we report a hybrid electrokinetic technique for manipulating mammalian cells in physiological fluids. This technique applies a combination of negative dielectrophoretic force and hydrodynamic drag force induced by electrohydrodynamics, which is effective in condu...
