Emissions analyser helps manage power station

by Quantitech Ltd  (Feb. 20, 2015)

A multiparameter emissions monitor at Thetford power station is being used to demonstrate to the Environment Agency that the plant is performing within the conditions of its environmental permit. However, the data from the analyser, which was supplied by Milton Keynes based Quantitech, also performs a vitally important role in helping to manage ...

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 ...

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 ...

Effect of streptavidin functionalised Fe 3 O 4 on the sedimentation of starch

by Inderscience Publishers  (Jan. 16, 2015)

Sedimentation velocity of starch was determined at three different pH in the presence of streptavidin functionalised Fe 3 O 4 nanoparticle. In the first step, the streptavidin functionalised Fe 3 O 4 nanoparticle was synthesised and characterised by various analytical techniques like Fourier transform infrared (FTIR) spectroscopy, X-ray ...

Gemas: Prediction of solid‐solution phase partitioning coefficients (Kd) for oxoanions and boric acid in soils using mid‐infrared diffuse reflectance spectroscopy

by John Wiley & Sons, Ltd.  (Dec. 5, 2014)

The authors' aim was to develop rapid and inexpensive regression models for the prediction of partitioning coefficients (Kd), defined as the ratio of the total or surface‐bound metal/metalloid concentration of the solid phase to the total concentration in the solution phase. Values of Kd were measured for boric acid (B(OH)30) and selected added ...

Monitoring greenhouse gases from biofuel crops

by Gasmet Technologies Oy  (Jan. 10, 2015)

Global issues such as climate change and energy security have driven rapid growth in renewable energy production - wind, solar, tidal, geothermal, hydro, biofuels etc. However, logically, each of these methods should deliver a net benefit in terms of greenhouse gas (GHG) reduction, so researchers in the United States have employed portable FTIR ...

Aerobic co-treatment of landfill leachate and domestic wastewater – are slowly biodegradable organics removed or simply diluted?

by IWA Publishing  (Dec. 19, 2014)

This study investigated the co-treatment of landfill leachate/domestic wastewater in bench-scale activated sludge (AS) reactors to determine whether the slowly biodegradable organic matter (SBOM) was removed rather than diluted. The AS reactors were loaded with mixtures of raw leachate and leachate that was pretreated by air stripping. The ...

FTIR resolution requirements for industrial gas analyses

by CIC Photonics, Inc.  (May 1, 2013)

FTIR Spectroscopy FTIR Spectroscopy is a widely used technique for gas analyses in industrial applications. It is a technique used in the semiconductor industry for measuring the purity of cleaning, etching, and epitreatment gases used with various process tools, reactors, and abatement devices. Among chemical companies and R&D faciltities, ...

Stabilisation of (3–mercaptopropyl)–trimethoxysilanecapped ZnS nanocrystals in polyacrylamide hydrogel

by Inderscience Publishers  (Feb. 2, 2015)

In this study, we synthesised ZnS nanocrystals and embedded them in polyacrylamide (PAAm) hydrogel to stabilise the fluorescence emission for biomedical applications. ZnS nanoparticles have strong emission but they lose it in time, so generally they are capped with polymers. We capped ZnS nanoparticles with (3–mercaptopropyl)–trimethoxysilane ...

Removal and recovery of lead (Pb2+) from industrial effluent using indigenous and tailor-made Aureobasidium sp. RBSS-303

by IWA Publishing  (Jan. 21, 2015)

The objective of this study was to assess the removal and recovery of Pb-II from industrial wastewater using a locally isolated strain of Aureobasidium sp. RBSS-303. The initial Pb2+ concentration of 600 mg/L resulted in maximum uptake capacity (Qmax 235.1 ± 0.3 mg/g). The biosorbent revival was attained by contacting with HCl ...
