3. 2. Sources and fluxes of organic contaminants in urban runoff

   Författare :Karin Björklund; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; alkylphenols; substance flow analysis; sediment; concentrations in urban matrices; urban runoff quality predictions; source identification; phthalates; stormwater; snow;

   Sammanfattning : Urban runoff quality is recognized as one of the most significant pressures on aquatic ecosystems worldwide. Research into pollutants in urban runoff has traditionally focused on nutrients, suspended solids and metals and consequently knowledge of anthropogenic organic pollutants is limited. LÄS MER

4. 3. Catalytic conversion of LignoBoost Kraft lignin into liquid products in near-critical water

   Författare :Huyen Nguyen Lyckeskog; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LignoBoost; Catalytic conversion; Hydrothermal conversion; Bio-oil; Near-critical water; Lignin;

   Sammanfattning : Lignin, one of the three main components of lignocellulosic biomass, is the second most abundant organic polymer found on Earth. Due to its aromatic nature, lignin is recognized as being a potential feedstock for producing transportation fuel and high value-added chemicals. LÄS MER

5. 4. An evaluation of sources contributing to urban runoff pollution

   Författare :Alexandra Müller; Maria Viklander; Helene Österlund; Jiri Marsalek; Shirley E. Clark; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stormwater quality; Pollution sources; Building surface materials; Traffic activities; Source identification methods; VA-teknik; Urban Water Engineering; Centrumbildning - Centrum för dagvattenhantering DRIZZLE ; Centre - Centre for Stormwater Management DRIZZLE ;

   Sammanfattning : Urban runoff is a significant pathway for the transport of diverse substances from the urban environment to receiving water bodies. Many of these substances are pollutants of environmental concern with potentially harmful effects on aquatic life. LÄS MER

7. 5. Recent Extraction Techniques with Emphasis on Supercritical Fluid Extraction and Microwave-assisted Extraction

   Författare :Cecilia Sparr Eskilsson; Centrum för analys och syntes; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytisk kemi; Analytical chemistry; Pressurized hot water extraction; Pressurized liquid extraction; Microwave-assisted extraction; Recent extraction techniques; Supercritical fluid extraction;

   Sammanfattning : Today’s requirements of fast, reliable and selective analytical methods with minimal usage of organic solvents have accelerated the development of new, automated extraction techniques. In this thesis recent extraction techniques with emphasis on supercritical fluid extraction (SFE) and microwave-assisted extraction (MAE) were investigated. LÄS MER
