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...

We present a numerical framework to solve the dynamic model for electrokinetic flows in microchannels using coupled lattice Boltzmann methods. The governing equation for each transport process is solved by a lattice Boltzmann model and the entire process is simulated through an iteration procedure. After validation, the present method is used to study the applicability of the Poisson–Boltzmann ...

The analysis of corticosterone in mouse blood serum (metabolic-stress experiment) and 17-hydroxycorticosterone in human urine (exercise-stress experiment) samples by means of capillary electrophoresis/UV absorbance in conjunction with online sample concentration techniques is described. The use of normal MEKC had an analyte detection limit of 7 microg/ml (S/N=3); whereas when online sample conc...

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...
