  • Evaluation of chitosan flakes as adsorbent for palladium and platinum recovery from binary dilute solutions

    In the recent years, special attention has been paid to the competitive recovery or separation of metals from industrial wastewaters or solid wastes that contain more than one chemical component. Platinum group metals (PGMs), particularly palladium and platinum, are used together in many fields such as industrial catalyst production. The recovery of these metals from industrial waste streams has ...

  • Anaerobic-aerobic treatment of toxic pulp effluents with biomass, immobilised on LEVAPOR carrier

    1. The problem Effluents of pulp mills using chlorine for pulp bleaching do contain several, under aerobic conditions only weakly degradable (35-45%) toxic chloroorganic pollutants. 2. The solution Preliminary biotretment tests under anaerobic conditions, using specially adapted microorganisms, immobilised on adsorbing, porous LEVAPOR carrier showed a remarkably ...

  • A review on the removal of antibiotics by carbon nanotubes

    Increasing concerns have been raised regarding the potential risks of antibiotics to human and ecological health due to their extensive use. Carbon nanotubes (CNTs) have drawn special research attention because of their unique properties and potential applications as a kind of adsorbents. This review summarizes the currently available research on the adsorption of antibiotics on CNTs, and will ...

  • Directed self-organisation of soluble proteins on surfaces

    Incorporation of proteins on surfaces is a first step in the lengthy process of using active biological molecules in man-made nanodevices. There is therefore a strong motivation to develop strategies for organising active proteins on solid substrates and it is very desirable to take advantage of the principles of self-assembly. In the present work, I summarise two strategies to orient and ...

  • Dioxines and furanes - Case Study

    Example: Scrap copper recycling, cobalt for battery production Similar tasks: Metal recycling, roast processes, thermal waste disposal When recycling metals - as in scrap copper recycling (mostly cable material) - toxic waste gases often occur. The raw materials to be recycled are injected in a shaft kiln that emits dust, organic contaminants, carbon monoxide, dioxins as well as furans. A ...

  • Tricky track at the Tunnel case study

    OPEC solves Channel Tunnel pollution problem British Rail Network 'SouthEast' were faced with an unusual problem at a project they were handling for Rail Freight. At the new freight inspection yard at the UK end of the Channel Tunnel, which is designed solely for electric traction, the operators will initially be using heavy diesel locomotives. When stationary these ...

  • Development of on-line instruments for monitoring of methane and NMTHC at PPB and PPM levels without matrix effects

    Monitoring of methane and Non-Methane Total Hydrocarbons (NMTHC) is an important tool for process monitoring. In the microelectronics industry, the silicon substrates (wafers) are stored in containers, named FOUP (Front Opening Unified Pod) made in polymers (PC, PEEK, COP, PEI). Such materials are able to adsorb the Volatile Molecular Contaminants (VMC) and subsequently outgas these ones in ...

  • A clear solution - hiflow process for produced water treatment delivers outstanding results for Taylor energy

    Taylor Energy, which specializes in energy exploration and production in the Gulf of Mexico, utilized CETCO Oilfield Services new Hi-Flow technology to increase oil and gas production in a field where the existing facility was at capacity with the amount of produced water it could handle. The two phase Hi-Flow process works to treat produced oilfield wastewater by separating/adsorbing the small ...

  • RP18 as a Filter case study

    More than just an adsorbent fabric, RP18's special design qualities make it a good filter too. The construction of RP18 is such that there is a large amount of free space which allows water to pass through whilst retaining the oil. This has been illustrated also in 'A method for Cleaning Foreshores' case study. This fabric is useful where water flows are high and the amount of oil retained is ...

  • Yes, You Can Pick the Right TLC Plate – Part I

    “I’d like a box of TLC plates, please.” Sounds innocent enough, right? But when you have more than 500 plate options, things get a whole lot trickier. How do you dig through the layers (pun intended) to get the plates you need? TLC plates come in lots of fun forms and sizes—at least we think they’re fun! You can differentiate TLC plates by: Adsorbent material ...

  • Inland diesel spill case study

    Introduction In January 2000 an oil spill occurred in the North of England. It was estimated up to 30,000 litres of diesel fuel had escaped the fuel storage tanks of a major factory due to a burst pipe. Fortunately most of the spilled oil found its way to a nearby drainage facility owned by the local Water Authority. Due to neglect the drainage outlet pipe that feeds ...

  • Emergency equipment for the absorption of chlorine in hospitals - Case Study

    Chlorine is a strong oxidant that in normal conditions and in its pure state formsdichlorine, a toxic gas with a yellow-greenish colour formed by diatomic molecules (Cl2) that are about 2.5 times heavier than air and have an unpleasant smell. Among its multiple applications and due to its powerful oxidising nature, it is widely used forwater purificationin sewage treatment plants and as ...

  • Properties and Behavior of Inorganics in Contaminated Soil

    Often, specific technologies may be ruled out, or the list of potential technologies may be immediately narrowed, on the basis of the presence or absence of one or more of the chemical groups. The relative amounts of each may tend to favor certain technologies. Metals may be found in the elemental form, but more often they are found as salts mixed in the soil. At the present time, treatment ...

  • CombiFlash Gradient Methods

    Abstract Purifying compounds require two processes: the actual purification and drying the sample afterwards. Several gradient methods were evaluated on a reaction mixture to evaluate run time and number of fractions to collect the desired compound. Reducing the volume of fractions is important to reduce the time required to dry the purified material. On large runs, drying time may be ...

  • Offshore oil spill clean up case study

    In the event of a major incident occurring offshore, for example a tanker casualty running aground or breaking up for any reason, it is of paramount importance to deploy emergency response to protect and save human life. Once this has been done an assessment of the casualty should be made on whether it is possible to salvage the vessel and its contents and to assess the type and amount of oil ...

  • Inland oil spill clean up case study

    Introduction The essential strategy for inland spill clean up techniques should be containment, recovery and temporary storage. Secondary needs will include transportation and possible disposal - or recycling. It is important to discover the source of the spill which might not be straight forward. A steady slow seepage from a leaking disused oil storage tank may be very difficult ...
