The aim of this study was the assessment of reduction of chemical oxygen demand (COD) from micro-polluted water using activated carbon-attapulgite composite adsorbent prepared using activated carbon a...
Reduction of CO2 emissions and associated abatement costs in the European lime industry.
Japan signed the United Nations Framework Convention on Climate Change (UNFCCC) at the World Summit in Rio de Janeiro in 1992 and expressed its determination to promote efforts for reducing the releas...
Abstract: Chromium(VI) in the environment is of particular concern because it is toxic to both plants and animals, even at low concentrations. As a redox-sensitive element, the fate and toxicity of ch...
Abstract: A model to compensate the 2:1 layer having excess negative charge owing to the reduction of Fe3+ to Fe2+ by sodium dithionite buffered with citrate-bicarbonate in nontronite, beidellite, and...
Abstract: The reduction of hexavalent chromium species in aqueous solutions by interaction with Fe(II)-bearing solid surfaces was studied using a 0.96 × l0−3 M Cr(VI) solution and iron-rich clay...
Previous studies have documented dissimilatory growth of bacteria on solid Mn41 oxide,but Mn31 oxides have not been previously studied; here we have demonstrated for the first time the bacterial reduc...
Microbiologic reduction of synthetic and geologic Fe31 oxides associated with four Pleis-tocene-age, Atlantic coastal plain sediments was investigated using a dissimilatory Fe reducing bacterium ( She...
Problems associated with intermittent and variable degrees of sample blackening are often reported for studies involving the preparation of CO2-bearing silicate glasses in pis-ton-cylinder apparatus. ...
Significant advances have been made in hydrofluoric acid solution calorimetry at La-fayette College in the past 15 years. To determine the degree to which these developments enable the reduction of sa...
Abstract: Ferruginous beidellites with Al:Fe atomic ratios up to 2.36 were obtained when solutions containing Al, Fe2+ and H4SiO4 were adjusted to pH 8.5 with Ca(OH)2 and incubated at 95 癈 in the pres...
In the 12 km2 catchment area of Syv creek, Denmark, moderate to high concentrations of nitrate (NO3−) occurred in the upper part of the oxidized zone (oxic-I), but dropped within the lower subox...
Abstract: Shewanella putrefaciens is a species of metal-reducing bacteria with a versatile respiratory metabolism. This study reports that S. putrefaciens strain MR-1 rapidly reduces Fe(III) within sm...
Abstract: Redox cycles are common in nature and likely have a profound effect on the behavior of soils and sediments. This study examined a key component of redox cycles in smectites, namely, the reox...
The oxidation state of structural iron greatly influences the physical-chemical properties of clay minerals, a phenomenon that may have significant implications for pollutant fate in the environment, ...
