FTIR emissions analyser helps manage UK power station

by Quantitech Ltd  (May 14, 2015)

A Gasmet FTIR multiparameter emissions monitor at Thetford power station is being used to demonstrate that the plant is performing within the conditions of its environmental permit. However, the data from the analyser, which was supplied by Gasmet’s UK distributor Quantitech, also performs a vitally important role in helping to manage the ...

Transformation of graphene oxide by ferrous iron: Environmental implications

by John Wiley & Sons, Ltd.  (May 5, 2015)

Abiotic transformation of graphene oxide (GO) in aquatic environments can markedly affect the fate, transport, and effects of GO. We observed that ferrous iron (Fe(II))—an environmentally abundant, mild reductant—can significantly affect the physicochemical properties of GO (examined by treating aqueous GO suspensions with Fe2+ at room ...

Preparation of cationic starch microspheres and study on their absorption to anionic-type substance

by IWA Publishing  (May 18, 2015)

Cationic starch microspheres (CSMs) were prepared from lab-made neutral starch-based microspheres using a cationic adsorbent, namely 3-chloro-2-hydroxypropyltrimethyl ammonium chloride, as the cationic etherifying agent. Detection by scanning electron microscopy, Fourier transform infrared spectroscopy (FTIR), and laser diffraction techniques ...

Application of novel consortium TSR for treatment of industrial dye manufacturing effluent with concurrent removal of ADMI, COD, heavy metals and toxicity

by IWA Publishing  (May 7, 2015)

The present study was aimed towards the effective bio-treatment of actual industrial effluent containing as high as 42,000 mg/L COD (chemical oxygen demand), >28,000 ADMI (American Dye Manufacturers Institute) color value and four heavy metals using indigenous developed bacterial consortium TSR. Mineral salt medium supplemented with as ...

Transformation characteristics of organic pollutants in Fered-Fenton process for dry-spun acrylic fiber wastewater treatment

by IWA Publishing  (Dec. 19, 2014)

The Fered-Fenton process using Ti sheet as cathode and RuO2/Ti as anode was employed for the pretreatment of dry-spun acrylic fiber manufacturing wastewater. The effects of feeding mode and concentration of H2O2 on chemical oxygen demand (COD) removal efficiency as well as the biodegradability variation during the Fered-Fenton process were ...

Characterization of modified PVDF membrane by gamma irradiation for non-potable water reuse

by IWA Publishing  (Mar. 27, 2015)

Poly(vinylidene fluorine) (PVDF) membranes were grafted by gamma-ray irradiation and were sulfonated by sodium sulfite to modify the surface of the membranes. The characteristics of the modified PVDF membranes were evaluated by the data of Fourier transform infrared (FT-IR), X-ray photoelectron spectroscopy (XPS), field-emission scanning ...

Enhanced photobactericidal activity of ZnO nanorods modified by meso-tetrakis(4-sulfonatophenyl)porphyrin under visible LED lamp irradiation

by IWA Publishing  (Apr. 27, 2015)

In this study, zinc oxide (ZnO) nanorods have been synthesized using a simple template-free precipitation technique and deposited on glass substrate. The meso-tetrakis(4-sulfonatophenyl)porphyrin (TPPS) has been synthesized and then immobilized on the surface of ZnO nanorods to prepare an organic/inorganic composite. The samples were ...

The African crested rat’s poisonous hairs studied by attenuated total reflection infrared spectroscopy case study

by Specac Limited  (Nov. 25, 2014)

Introduction Plant toxins are commonly used by many invertebrates, as an effective defence against predation. However, such behaviour has recently been observed in a mammal.1 The African crested rat, Lophiomys imhausi, applies a potent toxin to the fur alongside its flanks. It acquires this toxin from Acokanthera schimperi,1 a shrub abundant in ...

Activated charcoal–magnetic nanocomposite for remediation of simulated dye polluted wastewater

by IWA Publishing  (May 7, 2015)

Herein, we report a straightforward way to fabricate activated charcoal–magnetic nanocomposite (AC–MNC) by chemical precipitation for the sequestration of methylene blue (MB) from a simulated solution. The synthesised nanocomposite was characterised by Fourier transform infra-red (FTIR), Brunauer–Emmett–Teller (BET), ...
