“…(Saichek and Reddy 2005 ). Bioremediation, ultrasonic technology and Lasagna technologies were also integrated with EK remediation to remove 75-95 % organic pollutants (Ho et al 1995 ;Luo et al 2006 ;Huang et al 2012 ).…”

Though several in-situ treatment methods exist to remediate polluted sites, selecting an appropriate site-specific remediation technology is challenging and is critical for successful clean up of polluted sites. Hence, a comprehensive overview of all the available remediation technologies to date is necessary to choose the right technology for an anticipated pollutant. This review has critically evaluated the (i) technological profile of existing in-situ remediation approaches for priority and emerging pollutants, (ii) recent innovative technologies for on-site pollutant remediation, and (iii) current challenges as well as future prospects for developing innovative approaches to enhance the efficacy of remediation at contaminated sites.

“…This geometrical wall effect can be explained by the decrease of packing order as the distance from the wall increases and may have a strong impact on the macroscopic flow heterogeneity, axial dispersion, and particle-to-fluid heat and mass transfer, especially at aspect ratios, d c /d p , below 15 [69±74] when this critical wall region occupies a substantial fraction of the column. Since radial variations of transport properties have a far more serious effect on column performance than axial ones, this packing aspect will be quite important for capillary HPLC, but may have less impact on a macroscopic velocity inequality of the flow pattern in CEC.…”

The chromatographic performance with respect to the flow behavior and dispersion in fixed beds of nonporous and macroporous particles (having mean intraparticle pore diameters of 41, 105, and 232 nm) has been studied in capillary HPLC and electrochromatography. The existence of substantial electroosmotic intraparticle pore flow (perfusive electroosmosis) in columns packed with the macroporous particles was found to reduce stagnant mobile mass transfer resistance and decrease the global flow inhomogeneity over the column cross-section, leading to a significant improvement in column efficiency compared to capillary HPLC. The effect of electroosmotic perfusion on axial dispersion was shown to be sensitive to the mobile phase ionic strength and mean intraparticle pore diameter, thus, on an electrical double layer interaction within the particles. Complementary and consistent results were observed for the average electroosmotic flow through packed capillaries. It was found to depend on particle porosity and distinct contributions to the electrical double layer behavior within and between particles. Based on these data an optimum chromatographic performance in view of speed and efficiency can be achieved by straightforward adjustment of the electrolyte concentration and characteristic intraparticle pore size.

“…Another approach under extensive RD&D is the in situ remediation of contaminated subsurface zones by application of the Lasagna process. 51 This process has the basic configuration that resembles the pasta dish from which its name was derived. A subsurface reactor of high permeability is established using techniques such as hydraulic fracturing to create horizontal zones above and below (but in close proximity to) the contamination zone.…”

“…Reported results to date on the Lasagna process 51 have been limited to bench-scale testing. One series of tests showed that electroosmosis could flush an organic contaminant (para nitrophenol) uniformly from clay soil into adjacent permeable layers.…”
