  1. 11. Material identification using X-ray diffraction

    University essay from Mittuniversitetet/Institutionen för elektronikkonstruktion

    Author : Linda Genetu Teggen; [2019]
    Keywords : XRD; XRF; incineration; wastemanagement; toxic elements; pollution detection; fly ash; ash; Bruker D2Phaser; DIFFRAC.EVA; chemical filter; scan file.;

    Abstract : This study reviews the theoretical and experimental aspects of the X-ray diffraction (XRD) technique and evaluates its use in identifying toxic elements or compounds in waste that has been incinerated. Many industries incinerate materials that contain large significant amounts of toxic elements, and these elements should be identified and re-moved to reduce environmental pollution. READ MORE

Wind energy is one of the most promising energy resources as it is free from pollution, clean and probably will arise as one of the main energy sources to prevent global warming from happening. Almost 10% of the global energy demand is coming from renewable resources. READ MORE

  4. 13. Microbial binding of per- and polyfluorinated alkyl substances (PFASs) : - Analysis of PFASs in microbes with ultra-performance liquid chromatography – tandem mass spectrometry (UPLC-MS/MS)

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Karolina Majdak; [2018]
    Keywords : PFASs; microbes; microbial binding; PFOS; PFHxS; AFFFs.;

    Abstract : Per- and polyfluorinated alkyl substances (PFASs) belong to a large group of man-made chemicals that pollute the environment. Perfluorooctane sulfonic acid (PFOS) and perfluorooctanoic acid (PFOA) are the most commonly found PFASs. The pollution of PFASs can be caused among others by using of aqueous fire-fighting foams (AFFFs). READ MORE
