A series of batch tests were conducted to investigate the relative desorption potential of mercury from kaolin and glacial till soils under the effect of three extractant agents, namely, KI, NaEDTA and NaCl (all of them with a concentration of 0.1 M). These tests were conducted under different pH conditions (within a pH range between 2 and 12). Also batch tests using deionized water were perfor...

1. The electrophoretic velocities of gelatin-, egg-albumin-, and gliadin-covered quartz particles in various alcohol-water solutions are, within the limits employed in usual experimental procedures, proportional to the field strength. 2. The electrophoretic mobilities of small, irregularly shaped quartz particles covered with an adsorbed film of protein in alcohol-water solutions are equal to t...

In recent years different electrokinetic cell models for concentrated colloidal suspensions in aqueous electrolyte solutions have been developed. They share some of its premises with the standard electrokinetic model for dilute colloidal suspensions, in particular, neglecting both the specific role of the so-called added counterions (i.e., those released by the particles to the solution as they...

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...

Discrete fluid volumes (plugs) are often needed for micro bioassay. Current methods of isolating discrete volumes use electrokinetic forces that require high voltages and result in ionic component separation of the sample. Pressure-driven flow through a double-T metering junction is a suggested alternative to this electrokinetic method. There has been no extensive analysis of pressure-driven pl...

Affinity capillary electrophoresis has become an established approach for performing interaction studies. In affinity electrokinetic chromatography the retention factor, as in liquid chromatography, is useful for describing the migration behavior of the analytes, and is instrumental for assessing the affinity of an analyte for the pseudo-stationary phase. Erroneous use of the retention factor c...

The electrokinetic remediation method can function as a primary or secondary technology and be applied in conjunction with other physical biological methods, such soil washing, phytoremediation, bioremediation. Environmental impacts arising from the process determined using life cycle assessment analysis (LCA) tools. This study compared conventional strategy two hybrid strategies: electrokineti...
