Influence of EDTA on the Electrochemical Removal of Mercury (II) in Soil

Abstract: The removal of mercury from soil and Ca-bentonite was performed using electrochemical treatment adding ethylendiamine- tetra acetic acid (EDTA) as a complexing agent to improve the elec- trochemical removal of Hg (II) in soil from San Joaquin, Queretaro, Mexico. During the electrokinetic treatment in the presence of 0.1 M EDTA, most of Hg (II) migrates toward the anode obtaining the high- est removal efficiencies close to 70 % in bentonite after 9 h. Using 0.1M HCl only 65 % efficiency was attained after 13 h in the cathodic side. EDTA formed a negatively charged stable complex that migrates to the cathode by the application of the electrokinetic treatment across Hg - EDTA synthesized complex.

pH-dependent biosynthesis of copper oxide nanoparticles using Galphimia glauca for their cytocompatibility evaluation

Abstract: Copper oxide nanoparticles possess a high absorption coefficient and are non-toxic to animal cells. Biological agents inhabit many compounds that can be explored for the synthesis of monodispersed and non-toxic copper oxide nanoparticles. This is the most important advantage of biological syntheses over physical and chemical methods. In the present work, copper oxide nanoparticles have been synthesized with a simple and green technique by using an aqueous extract of mixed leaf and flowers of Galphimia glauca. The nanoparticles were synthesized at 80 °C, with a 15 mM Copper sulfate solution and at varying pH range (2, 4, inherent, i.e. 5.3, 8, 10, 12). The particle size of the nanoparticles was confirmed to be 5-10 nm using TEM and XRD at pH 12. The functional groups on the surface of the nanoparticles were characterized using FTIR. Moreover, GCMS analysis of the aqueous extracts showed that different flavonoids were responsible for the biosynthesis of copper oxide nanoparticles. The cytotoxicity assays were also determined using MRC-5 and HeLa cell lines for copper oxide nanoparticles and was found that the nanoparticles are non-toxic to the normal cells and are relatively toxic to cancer cells.

Experimental study and mathematical modeling of two phase flow with a Eulerian approach in a continuous gas evolving electrochlorinator

Abstract: Electrochlorination systems have become popular. Their hydrodynamic behavior affects the efficiency and power consumption but the reaction environment is complex due to the complex flow arising from gas evolution at the electrodes. Water reduction at the stainless steel cathode generates a large amount of small hydrogen bubbles being then, the only evolving gas at the electrodes that can modify the flow pattern inside the reactor. (Cl2(g) generated at anode is rapidly hydrolyzed into hypochlorous acid or hypochlorite ion). This paper considers the hydrodynamic behavior of the two-phase flow using experimentally and modeled RTD curves, via a weakly coupled Euler-Euler model. Experimental data are in a qualitative agreement with the RTD model.
