With the current increasing interest in aquifer denitrification, recent attention has been given to cost‐effective in‐situ treatments such as Enhanced In‐Situ Biological Denitrification (EISBD), which intends stimulate indigenous bacterial activity by injecting an external organic substrate and/or nutrients matrix. Within this context, laboratory batch assays have conducted develop a strategy for denitrification of nitrate‐contaminated Argentona, Catalonia (Spain). The were run under aerobic...
The photophysical properties of 2,4,6-triphenylpyrylium (TPP+) and three para-substituted tritylium ions encapsulated within Y, β, MCM-41 have been studied. It was found that TPP+ adsorbed or silica only emits fluorescence (λmax 470 nm), whereas when this cation is incorporated HY LaY, simultaneous emission room-temperature phosphorescence 560 nm) observed. decay consists two consecutive first-order processes dominated by the fast (0.2−0.7 ns) component. In addition to prompt fluorescence,...
Long-term performance assessment of nuclear waste repositories is affected by the ability outer barrier systems to retain radionuclides after possible corrosive leakage containers. The mobility released from spent fuel depends strongly on processes that take place in backfill material. interaction steel corrosion products and part such a scenario. In this work, sorption Th(IV) onto 2-line-ferrihydrite (FeOOH·H2O) magnetite (Fe3O4), used as models for products, has been studied using EXAFS...
Abstract A restored riparian zone was characterized to understand the effects of flooding on subsurface hydrological flow paths and nitrate removal in groundwater. Field laboratory investigations were combined with numerical modeling dynamic reactive transport. Flooding enhances groundwater primarily by two mechanisms. First, creating a stagnant beneath flooded area thereby increasing residence time leaving more for removal. Secondly, is increased enhancing upward into highly organic‐rich...
Abstract The sorption kinetics of antimony(V) on synthetic goethite is very fast compared to the other metals (e.g. arsenic and selenium) depends temperature, with an activation energy 49±9 kJ · mol−1 in temperature range 15–35°C. Sorption isotherms have been developed at different temperatures ionic strength values. results modelled using a Langmuir isotherm there not considerable influence neither studied (15°C–35°C), nor (between 0.001 0.01 mol dm−3). high pH values lower than 8, more...
Spatial distributions of fifteen trace elements (As, Be, Cd, Co, Cr, Cu, Mo, Ni, Pb, Sb, Sn, Tl, U, V, and Zn) potentially harmful for the human health ecosystem have been studied in soils Catalonia. Geographic Information Systems were used together with cartographic information available sampling design. Descriptive statistics, box-plots, cumulative distribution figures to assess differences element concentrations among soil uses. A clear enrichment Pb Sn (mean 24.3 3.31 mg · kg−1 d.w.,...
The formation of uranyl-peroxide complexes was studied at alkaline media by using UV-Visible spectrophotometry and the STAR code. Two different were found a H2O2/U(VI) ratio lower than 2. A graphical method used in order to obtain constants such program refine values because its capacity treat multiwavelength absorbance data refining equilibrium constants. obtained for two identified were: UO22+ + H2O2 4OH− ⇆ UO2(O2)(OH)22− 2H2O: log β°1,1,4 = 28.1 ± 0.1 (1)UO22+ 2H2O2 6OH− UO2(O2)2(OH)24−...
Article Kinetic Studies of Unirradiated UO2 Dissolution under Oxidizing Conditions in Batch and Flow Experiments was published on December 1, 1994 the journal Radiochimica Acta (volume 66-67, issue s1).
Carbon-nanofiber-based screen-printed electrodes modified with silver nanoparticles (Ag-NP-SPCNFEs) were tested in a pioneering manner for the direct determination of As(V) at low μg L−1 levels by means differential pulse anodic stripping voltammetry. Screen-printed two different types Ag-NPs, nanoseeds (NS), and nanoprisms (NPr) characterized both microscopically electrochemically. Furthermore, after optimizing voltammetric As(V), analytical performance considered sensors was compared...
