Selectivity and Mass Transfer Limitations in Pressure-Retarded Osmosis at High Concentrations and Increased Operating Pressures

02-Oct-2015 | Anthony P. Straub; Chinedum O. Osuji; Tzahi Y. Cath; Menachem Elimelech, Environmental Science & Technology, 2015

Pressure-retarded osmosis (PRO) is a promising source of renewable energy when hypersaline brines and other high concentration solutions are used. However, membrane performance under conditions suitable for these solutions is poorly understood. In this work, we use a new method to characterize ...


Knockdown of Fruit Flies by Imidacloprid Nanoaerosol

01-Oct-2015 | Victor N. Morozov; Igor L. Kanev, Environmental Science & Technology, 2015

This report describes the effects of nanoaerosol particles (NAPs) from imidacloprid (IMI) on fruit flies. NAPs were produced using a newly developed generator which employs electro-hydrodynamic atomization of IMI solution in ethanol. Exposure of Drosophila melanogaster to the IMI NAPs at a ...


Synergetic Transformations of Multiple Pollutants Driven by Cr(VI)–Sulfite Reactions

29-Sep-2015 | Bo Jiang; Yukun Liu; Jingtang Zheng; Minghui Tan; Zhaohui Wang; Mingbo Wu, Environmental Science & Technology, 2015

Reduction of Cr(VI) is often deemed necessary to detoxify chromium contaminants; however, few investigations utilized this reaction for the purpose of treating other industrial wastewaters. Here a widely used Cr(VI)–sulfite reaction system was upgraded to simultaneously transform multiple ...


Scaling-Free Electrochemical Production of Caustic and Oxygen for Sulfide Control in Sewers

24-Sep-2015 | Hui-Wen Lin; Korneel Rabaey; Jürg Keller; Zhiguo Yuan; Ilje Pikaar, Environmental Science & Technology, 2015

Caustic shock-loading and oxygen injection are commonly used by the water industry for biofilm and sulfide control in sewers. Caustic can be produced onsite from wastewater using a two-compartment electrochemical cell. This avoids the need for import and storage of caustic soda, which typically ...


Fractionation of Selenium during Selenate Reduction by Granular Zerovalent Iron

15-Sep-2015 | Heather K. Shrimpton; David W. Blowes; Carol J. Ptacek, Environmental Science & Technology, 2015

Batch experiments were conducted using granular zerovalent iron (G-ZVI) with either ultrapure water or CaCO3 saturated simulated groundwater to assess the extent of Se isotope fractionation in solution under the anaerobic conditions characteristic of many aquifers. G-ZVI is a common remediation ...


Facilitated Leaching of Additive-Derived PBDEs from Plastic by Seabirds’ Stomach Oil and Accumulation in Tissues

10-Sep-2015 | Kosuke Tanaka; Hideshige Takada; Rei Yamashita; Kaoruko Mizukawa; Masa-aki Fukuwaka; Yutaka Watanuki, Environmental Science & Technology, 2015

Our previous study suggested the transfer of polybrominated diphenyl ether (PBDE) flame retardants from ingested plastics to seabirds’ tissues. To understand how the PBDEs are transferred, we studied leaching from plastics into digestive fluids. We hypothesized that stomach oil, which is present ...


Biostimulation by Glycerol Phosphate to Precipitate Recalcitrant Uranium(IV) Phosphate

02-Sep-2015 | Laura Newsome; Katherine Morris; Divyesh Trivedi; Alastair Bewsher; Jonathan R Lloyd, Environmental Science & Technology, 2015

Stimulating the microbial reduction of aqueous uranium(VI) to insoluble U(IV) via electron donor addition has been proposed as a strategy to remediate uranium-contaminated groundwater in situ. However, concerns have been raised regarding the longevity of microbially precipitated U(IV) in the ...


Removal of Antimonite (Sb(III)) and Antimonate (Sb(V)) from Aqueous Solution Using Carbon Nanofibers That Are Decorated with Zirconium Oxide (ZrO2)

28-Aug-2015 | Jinming Luo; Xubiao Luo; John Crittenden; Jiuhui Qu; Yaohui Bai; Yue Peng; Junhua Li, Environmental Science & Technology, 2015

Zirconium oxide (ZrO2)-carbon nanofibers (ZCN) were fabricated and batch experiments were used to determine antimonite (Sb(III)) and antimonate (Sb(V)) adsorption isotherms and kinetics. ZCN have a maximum Sb(III) and Sb(V) adsorption capacity of 70.83 and 57.17 mg/g, respectively. The adsorption ...


Enhanced Salt Removal in an Inverted Capacitive Deionization Cell Using Amine Modified Microporous Carbon Cathodes

27-Aug-2015 | Xin Gao; Ayokunle Omosebi; James Landon; Kunlei Liu, Environmental Science & Technology, 2015

Microporous SpectraCarb carbon cloth was treated using nitric acid to enhance negative surface charges of COO– in a neutral solution. This acid-treated carbon was further modified by ethylenediamine to attach −NH2 surface functional groups, resulting in positive surface charges of −NH3+ via ...


Probing Contaminant Transport to and from Clay Surfaces in Organic Solvents and Water Using Solution Calorimetry

26-Aug-2015 | Amin Pourmohammadbagher; John M. Shaw, Environmental Science & Technology, 2015

Clays, in tailings, are a significant ongoing environmental concern in the mining and oilsands production industries, and clay rehabilitation following contamination poses challenges episodically. Understanding the fundamentals of clay behavior can lead to better environmental impact mitigation ...
