Adsorption of CO2, CH4, and N2 on Ordered Mesoporous Carbon: Approach for Greenhouse Gases Capture and Biogas Upgrading
08-05-2013 | Bin Yuan; Xiaofei Wu; Yingxi Chen; Jianhan Huang; Hongmei Luo; Shuguang Deng, Environmental Science & Technology, 2013
Separation of CO2 and N2 from CH4 is significantly important in natural gas upgrading, and capture/removal of CO2, CH4 from air (N2) is essential to greenhouse gas emission control. Adsorption equilibrium and kinetics of CO2, CH4, and N2 on an ordered mesoporous carbon (OMC) sample were ...
Antagonistic Effects of Humic Acid and Iron Oxyhydroxide Grain-Coating on Biochar Nanoparticle Transport in Saturated Sand
07-05-2013 | Dengjun Wang; Wei Zhang; Dongmei Zhou, Environmental Science & Technology, 2013
Biochar land application may result in multiple agronomic and environmental benefits (e.g., carbon sequestration, improving soil quality, and immobilizing environmental contaminants). However, our understanding of biochar particle transport is largely unknown in natural environments with ...
Coagulation Kinetics of Humic Aggregates in Mono- and Di-Valent Electrolyte Solutions
01-05-2013 | Long-Fei Wang; Ling-Ling Wang; Xiao-Dong Ye; Wen-Wei Li; Xue-Mei Ren; Guo-Ping Sheng; Han-Qing Yu; Xiang-Ke Wang, Environmental Science & Technology, 2013
Coagulation behaviors of humic acids (HAs) aggregates in electrolyte solutions at different pHs, valences and concentrations of electrolyte cations were investigated using dynamic light scattering technique in combination of other analytical tools. For monovalent electrolyte sodium chloride ...
Joint Photomicrobial Process for the Degradation of the Insensitive Munition N-Guanylurea-dinitramide (FOX-12)
01-05-2013 | Nancy N. Perreault; Annamaria Halasz; Sonia Thiboutot; Guy Ampleman; Jalal Hawari, Environmental Science & Technology, 2013
N-Guanylurea-dinitramide (FOX-12) is a very insensitive energetic material intended to be used in the composition of next-generation insensitive munitions. To help predict the environmental behavior and fate of FOX-12, we conducted a study to determine its photodegradability and ...
Influence of Chloride and Fe(II) Content on the Reduction of Hg(II) by Magnetite
26-04-2013 | Timothy S. Pasakarnis; Maxim I. Boyanov; Kenneth M. Kemner; Bhoopesh Mishra; Edward J. O’Loughlin; Gene Parkin; Mich ..., Environmental Science & Technology, 2013
Abiotic reduction of inorganic mercury by natural organic matter and native soils is well-known, and recently there is evidence that reduced iron (Fe) species, such as magnetite, green rust, and Fe sulfides, can also reduce Hg(II). Here, we evaluated the reduction of Hg(II) by magnetites with ...
Photocatalytic Conversion of Gaseous Nitrogen Trichloride into Available Chlorine—Experimental and Modeling Study
22-04-2013 | F. Gérardin; A. Cloteaux; M. Guillemot; M. Faure; J. C. André, Environmental Science & Technology, 2013
In water, chlorine reacts with nitrogen-containing compounds to produce disinfection byproducts such as nitrogen trichloride which induces ocular and respiratory irritations in swimming pool workers. A technical solution has been used to reduce NCl3 exposure to acceptable levels, by adding a ...
Effects of Solution Chemistry on the Transport of Graphene Oxide in Saturated Porous Media
10-04-2013 | Jacob D. Lanphere; Corey J. Luth; Sharon L. Walker, Environmental Science & Technology, 2013
A transport study was performed in saturated porous media through a packed bed column to simulate fate of graphene oxide nanoparticles (GONPs) in the subsurface environment. Transport experiments, along with mass balances and column dissections, were conducted as a function of ionic strength ...
Lead Uptake in Diverse Plant Families: A Study Applying X-ray Absorption Near Edge Spectroscopy
10-04-2013 | Gudrun L. Bovenkamp; Alexander Prange; Wolfgang Schumacher; Kyungmin Ham; Aaron P. Smith; Josef Hormes, Environmental Science & Technology, 2013
The chemical environment of lead in roots and leaves of plants from four different plant families and a lichen from a former lead mining site in the Eifel Mountains in Germany was determined by Pb L3-edge XANES measurements using solid reference compounds and also aqueous solutions of ...
Halogenation of Bisphenol-A, Triclosan, and Phenols in Chlorinated Waters Containing Iodide
09-04-2013 | Peter J. Vikesland; E. Matthew Fiss; Krista R. Wigginton; Kristopher McNeill; William A. Arnold, Environmental Science & Technology, 2013
Free chlorine reacts with the iodide (I–) present in disinfected waters to produce free iodine. Past research has indicated that this nonchlorinated oxidant exhibits greater reactivity and potentially produces more toxic byproducts than free chlorine alone. In this study, we examined the ...
Highly Sensitive Strategy for Hg2+ Detection in Environmental Water Samples Using Long Lifetime Fluorescence Quantum Dots and Gold Nanoparticles
03-04-2013 | Dawei Huang; Chenggang Niu; Min Ruan; Xiaoyu Wang; Guangming Zeng; Canhui Deng, Environmental Science & Technology, 2013
The authors herein described a time-gated fluorescence resonance energy transfer (TGFRET) sensing strategy employing water-soluble long lifetime fluorescence quantum dots and gold nanoparticles to detect trace Hg2+ ions in aqueous solution. The water-soluble long lifetime fluorescence quantum ...
