3. 2. Pelagic fish oil : methods for extraction and purification

   Kandidat-uppsats, SLU/Department of Molecular Sciences

   Författare :Linda Näsbom; [2020]
   Nyckelord :Pelagic fish; muscle; lipids; fish oil; pollution; purification; extraction.;

   Sammanfattning : The Pelagic fishes are a wide group of fishes that live in the open water. They could be divided in two groups depending on the size, the small forage fishes and the large predators. These fishes swim regularly and have muscles with high lipid content. There are two types of muscles in the fish. LÄS MER

4. 3. Development and application of a solidphase extraction method for simultaneousdetermination of PAHs, oxy-PAHs andazaarenes in water samples

   Master-uppsats, Kemiska institutionen

   Författare :Yu Wang; [2012]
   Nyckelord :;

   Sammanfattning : In this study, a solid phase extraction (SPE) method was developed that can be used to extract a wide range of polycyclic aromatic compounds (PACs), including polycyclic aromatic hydrocarbons (PAHs), oxygenated PAHs (oxy-PAHs) and azaarenes, from water samples. Three commercially available SPE materials, i.e. LÄS MER
