  1. 6. Minimization of chemical's release from a large-scale pharmaceutical industry : By optimization of the crystallization process

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Cecilia Rahn; [2021]
    Keywords : Minimization of release; pharmaceutical industry; crystallization; optimization; Minimering av utsläpp; läkemedelsindustri; kristallisation; optimering;

    Abstract : The presence of active pharmaceutical ingredients (APIs) and other chemicals in wastewater has caused concerns in recent years due to its potential risk to the environment and society. Thus, the aim of the study is to investigate ways to minimize the release of chemicals from a large-scale pharmaceutical industry to an industrial wastewater treatment plant. READ MORE

  3. 7. Evaluation of selected parameters of Total Oxidisable Precursor Assay on per- and polyfluoroalkyl substances

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Sofia Francois; [2021]
    Keywords : Per- and polyfluoroalkyl substances PFASs ; Total oxidisable precursor TOP assay; solidphase extraction SPE ; washing steps; PFAS precursor compounds.;

    Abstract : Per- and polyfluoroalkyl substances (PFASs) are man-made fluorinated compounds that havebeen detected in humans, the environment, and wildlife. The strong C-F bonds contribute tothe high thermal stability of some PFASs and make them extremely resistant to degradationunder normal environmental conditions. READ MORE

  4. 8. Oxidation of cellulose to favour its dissolution in alkaline aqueous solution before regeneration into textile yarn

    University essay from KTH/Kemiteknik

    Author : Martin Orpiszak; [2021]
    Keywords : Cellulose; periodate oxidation; dissolution; regeneration; textile yarn; cellulosa; natriumperjodat oxidation; upplösning; regenerering; textilgarn;

    Abstract : Detta examensarbete är en del av CelluFil-projektet och syftar till att optimera förhållandena för upplösning av cellulosa i vattenlösning av natriumhydroxid följd av regenering i form av ett garn. Tidigare arbeten har visa tatt cellulosa kan lösas i vattenlösning vid -10°C, men sådana förhållanden är inte tillämpliga i industriell skala. READ MORE

  5. 9. Removal of per- and polyfluoroalkyl substances(PFAS) from contaminated leachate usingaeration foam fractionation

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Axel Krögerström; [2021]
    Keywords : PFAS; Foam Fractionation; Leachate; Removal Efficiency; Wastewater Treatment;

    Abstract : Leachate from landfills is contaminated in many ways and per- and polyfluoroalkyl substances (PFAS)-contamination is one of them. Recent studies have demonstrated the environmental and human concerns of PFAS. Therefore, the treatment of leachate is important. READ MORE

  6. 10. Molecular linking towards direct plasmonic transparent solar cell

    University essay from Uppsala universitet/Institutionen för kemi - Ångström

    Author : Thinh Nguyen Luong The; [2020]
    Keywords : pABA; plasmonic; plasmon; solar; cell; Ag; silver; self; assembly; citrate;

    Abstract : Plasmonic materials have been studied extensively in the last decade for applications in photonics, solar energy utilization and catalysis. The introduction of molecular linker bridging metal particles and oxide semiconductor has been proven to prolong the lifetime of short-lived hot carriers and prevent issues from ohmic contact.
