Monolithic magnetic carbonaceous beads for efficient Cr(VI) removal from water

25-Nov-2015 | Zhimin Lei; Shangru Zhai; Qingda An; Yuan Fan; Jialiang Lv; Ce Gao; Zuoyi Xiao, New Journal of Chemistry, 2015

Monolithic, magnetic carbonaceous materials as adsorbents can provide easy recovery and quickly separate pollutants in wastewater treatment; however, the developing of designed fabrication process remains a great challenge. Herein, a super magnetic monolithic material was firstly synthesized via ...


Cellular and molecular hypoxic response in common carp (Cyprinus carpio) exposed to linear alkylbenzene sulfonate at sublethal concentrations

21-Nov-2015 | Junichi Tasaki, Kei Nakayama, Ichiyo Shimizu, Hiroko Yamada, Takahiro Suzuki, Naohiro Nishiyama, Masayuki Yamane, Environmental Toxicology, 2015

Abstract Linear alkylbenzene sulfonate (LAS) is an anionic surfactant commonly used in cleaning agents such as laundry detergents. Trace amounts of LAS are released into environmental waters after processing in wastewater treatment plants after the use of this chemical. Acute toxicity of LAS ...


Evidence for Anaerobic Dechlorination of Dechlorane Plus in Sewage Sludge

20-Nov-2015 | Ed Sverko; Brian McCarry; Robert McCrindle; Allison Brazeau; Miren Pena-Abaurrea; Eric Reiner; Shirley Anne Smyth; B ..., Environmental Science & Technology, 2015

The environmental occurrence of dechlorination moieties from the high production volume flame retardant, Dechlorane Plus (DP), has largely been documented; however, the sources have yet to be well understood. In addition, few laboratory-based studies exist which identify the cause for the ...


Impact of Heavy Metals on Transcriptional and Physiological Activity of Nitrifying Bacteria

05-Nov-2015 | Vikram Kapoor; Xuan Li; Michael Elk; Kartik Chandran; Christopher A. Impellitteri; Jorge W. Santo Domingo, Environmental Science & Technology, 2015

Heavy metals can inhibit nitrification, a key process for nitrogen removal in wastewater treatment. The transcriptional responses of amoA, hao, nirK, and norB were measured in conjunction with specific oxygen uptake rate (sOUR) for nitrifying enrichment cultures exposed to different metals ...


Widespread Microbial Adaptation to l-Glutamate-N,N-diacetate (L-GLDA) Following Its Market Introduction in a Consumer Cleaning Product

28-Oct-2015 | Nina R. Itrich; Kathleen M. McDonough; Cornelis G. van Ginkel; Ed C. Bisinger; Jim N. LePage; Edward C. Schaefer; Je ..., Environmental Science & Technology, 2015

l-Glutamate-N,N-diacetate (L-GLDA) was recently introduced in the United States (U.S.) market as a phosphate replacement in automatic dishwashing detergents (ADW). Prior to introduction, L-GLDA exhibited poor biodegradation in OECD 301B Ready Biodegradation Tests inoculated with sludge from U.S. ...


IJERPH, Vol. 12, Pages 13399-13412: Assessment of the Physicochemical Qualities and Prevalence of Escherichia coli and Vibrios in the Final Effluents of Two Wastewater Treatment Plants in South Africa: Ecological and Public Health Implications

23-Oct-2015 | Osuolale, Olayinka ; Okoh, Anthony, International Journal of Environmental Research and Public Health, 2015

The final effluents of two wastewater treatment plants (WWTPs) in the Eastern Cape Province of South Africa were evaluated for their physicochemical and microbiological qualities over a period of 12 months. The physicochemical parameters assessed ranged as follows both plants. The ranges of ...


Ultrathin g‐C3N4 Nanosheets Coupled with AgIO3 as Highly Efficient Heterostructured Photocatalysts for Enhanced Visible‐Light Photocatalytic Activity

22-Oct-2015 | Yunfeng Li, Kai Li, Yang Yang, Leijiao Li, Yan Xing, Shuyan Song, Rongchao Jin, Mei Li, Chemistry - A European Journal, 2015

Abstract The photocatalytic activity of graphite‐like carbon nitride (g‐C3N4) could be enhanced by heterojunction strategies through increasing the charge‐separation efficiency. As a surface‐based process, the heterogeneous photocatalytic process would become more efficient if a larger contact ...


Molecular Characterization and Transformation of Dissolved Organic Matter in Refinery Wastewater from Water Treatment Processes: Characterization by Fourier Transform Ion Cyclotron Resonance Mass Spectrometry

22-Oct-2015 | Yongyong Li; Zhi Fang; Chen He; Yahe Zhang; Chunming Xu; Keng H. Chung; Quan Shi, Energy & Fuels, 2015

A set of wastewaters sampled in a stream-by-stream flow of the process in a refinery wastewater treatment plant were characterized to investigate the molecular composition and transformation of dissolved organic matter (DOM). The samples were separated into organic and aqueous phase DOMs by ...


Ag3PO4/TiO2‐assisted degradation of malachite green in aqueous solution treated by dielectric barrier discharge plasma

20-Oct-2015 | Lu Xin, Yabing Sun, Jingwei Feng, Journal of Chemical Technology & Biotechnology, 2015

ABSTRACT BACKGROUND A new method of malachite green (MG) degradation by dielectric barrier discharge (DBD) plasma with an Ag3PO4/TiO2 composite photocatalyst was investigated. Ag3PO4/TiO2 was synthetized by an in situ precipitation method under room conditions, and analyzed by XRD, SEM, TEM, ...


Effects of Exposure to WwTW Effluents over Two Generations on Sexual Development and Breeding in Roach Rutilus rutilus

16-Oct-2015 | Patrick B. Hamilton; Anke Lange; Elizabeth Nicol; Lisa K. Bickley; Eliane S. R. De-Bastos; Susan Jobling; Charles R. ..., Environmental Science & Technology, 2015

Exposure to environmental estrogens in wastewater treatment works (WwTW) effluents induces feminized responses in male fish, including the development of eggs in male testes. However, the impacts on the offspring of exposed fish are not well understood. In this study, we examined whether roach ...
