  1. 1. Removal of PFASs and Uranium from Drinking Water Using SorbixTM Anion Exchange Resin : Effects of Sodium Chloride on the Removal Efficiency

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

    Author : Fawaz Rustum; [2021]
    Keywords : Perfluorinated; polyflourinated; adsorption; fluorotelomer; salt; perfluorerade; polyfluorerade; adsorption; fluorotelomer; salt;

    Abstract : The increasing awareness towards PFAS pollution makes it increasingly important to treat. Many agencies over the globe, including the Swedish Food Agency, are introducing ever so strict control over PFASs in drinking water. READ MORE

  3. 2. The dependence of chromatographic conditions for separation of oligonucleotides in different AEX-HPLC columns

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Keywords : ion exchange chromatography; oligonucleotides; anion exchange column; pH; HPLC; Jonbyteskromatografi; oligonukleotider; anjonbytarkolonn; pH; HPLC;

    Abstract : Oligonucleotides (ONs) are widely used in different applications in life science, forensic, in i.e. family tree DNA test for humans and in diagnostic applications in several fields. READ MORE

  4. 3. Development of separation method for analysis of oligonucleotides using LC-UV/MS

    University essay from Uppsala universitet/Analytisk farmaceutisk kemi

    Author : Björs Ida; [2018]
    Keywords : Oligonucleotides; UPLC; liquid chromatography; time of flight; mass spectrometry; reversed-phase weak anion exchange; AcclaimTM Mixed Mode WAX-1; DNAPacTM RP; ACQUITY UPLC BEH C18;

    Abstract : Introduction Oligonucleotides are short nucleic acid chains, usually 19-27mer long. They bind to their corresponding chain, making a specific inhibition possible. In pharmaceuticals, this can be used to inhibit the expression of a gene or protein of interest. READ MORE

  5. 4. Evaluation of the Removal Efficiency of Perfluoroalkyl Substances in Drinking Water

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Sophie Englund; [2015]
    Keywords : per- and polyfluoroalkyl substances; PFASs; anion exchange; activated carbon; drinking water; removal efficiency;

    Abstract : Per- and polyfluoroalkyl substances (PFASs) are chemicals that have been used for over 50 years. They are both hydrophobic and hydrophilic, which make them useful in a wide range of products, both in the domestic and industrial market. Recently, the global attention on PFASs has increased due to their possible harmful health effects on humans. READ MORE

  6. 5. Evaluation of the Removal Efficiency of Per- and Polyfluoroalkyl Substances in Drinking Water using Nanofiltration Membranes, Active Carbon and Anion Exchange

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Klara Lindegren; [2015]
    Keywords : PFASs; perfluoroalkyl substances; removal efficiency; NF; nanofiltration; membrane; GAC; granular activated carbon; AE; anion exchange; PFAS; perfluorerade alkylsubstanser; reningseffektivitet; NF; nanofiltrering; membran; GAC; granulärt aktivt kol; AE; jonbytarmassa;

    Abstract : Per- and polyfluoroalkyl substances (PFASs) is a group of man-made, highly persistent chemicals. Due to the specific surface-active attributes of these molecules, applications are numerous and feed an economically important industry. During the last decade, PFASs have been detected globally in the environment, living organisms and tap water. READ MORE
