  • The determination of total mercury in whole blood using thermal decomposition and amalgamation coupled with atomic absorption

    Mercury has long been recognized as a serious global pollutant that has a significant impact upon our ecosystem. Unlike most other pollutants, it is highly mobile, nonbiodegradable, and bio-accumulative and as a result has to be closely monitored to ensure its harmful effects on local populations are minimized. Approximately 50 tons of mercury particulates are emitted into the atmosphere every ...

  • Treatment of textile effluents by chloride-intercalated Zn-, Mg- and Ni-Al layered double hydroxides

    This work involved the preparation, characterization and dyes removal ability of Zn-Al, Mg-Al and Ni-Al layered double hydroxide (LDH) minerals intercalated by chloride ions. The materials were synthetized by the co-precipitation method. X-ray diffraction, Fourier transform infrared, thermogravimetric-differential thermal analysis and transmission electron microscopy characterization exhibited ...

  • Adsorption of heavy metals from aqueous solutions by Mg–Al–Zn mingled oxides adsorbent

    In our study, Mg–Al–Zn mingled oxides were prepared by the co-precipitation method. The structure, composition, morphology and thermal stability of the synthesized Mg–Al–Zn mingled oxides were analyzed by powder X-ray diffraction, Fourier transform infrared spectrometry, N2 physisorption, scanning electron microscopy, differential scanning calorimetry and thermogravimetry. Batch experiments ...

  • Enhanced separation of hop oils by flow-modulated GC×GC–TOF MS with Tandem Ionisation

    Beer contains hundreds of organic ingredients, with concentrations spanning many orders of magnitude, and including monoterpenes (C10) and sesquiterpenes (C15). These are aroma-active hydrocarbons found in the essential oils of various plants, including hops, and provide much of the characteristic ‘bitterness’ of the finished beer. Of the greatest importance for beer is the ...

  • Kinetic characterization, thermo-stability and Reactive Red 195A dye detoxifying properties of manganese peroxidase-coupled gelatin hydrogel

    An indigenous and industrially important manganese peroxidase (MnP) was isolated from solid-state bio-processing of wheat bran by white-rot fungal strain Ganoderma lucidum IBL-05 under pre-optimized growth conditions. Crude MnP extract was partially purified (2.34-fold) to apparent homogeneity by ammonium sulphate precipitation and dialysis. The homogeneous enzyme preparation was encapsulated ...

  • Phosphorus control protects surface waters

    Phosphorus is the decisive factor for excessive algae and plant growth in water bodies, that’s why quality standards require reductions in the amount of phosphorus released from wastewater treatment plants into rivers and lakes. In recent years, the outlet limit values have not only been reduced on national levels. Depending on the vulnerability of ecosystems, especially low target values ...

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

    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 East Africa and dubbed the “poison arrow ...

  • The Applications of an Industrial Drying Oven

    Industrial drying ovens are designed to simultaneously heat a material while withdrawing moisture from its surface, a process with many commercial, pharmaceutical, and industrial applications. These are primarily used for batch processes – though varying product or research requirements need vastly different mechanisms and components. However, there is a basic three-stage operating process ...

  • QuadOa and OGI: how EPA regulations are changing the way we look at gas leaks

    Earlier this year, the Environmental Protection Agency (EPA) published Regulation 40 CFR, Part 60, Sub-part OOOOa, commonly known as Quad Oa, and finally brought optical gas imaging (OGI) firmly into the mainstream. This presents a major shift in the way fugitive emissions are regulated, and the technology that can be used.  Detecting and acting on gas leaks is naturally a major ...
