  2. 1. Size Characterisation of Water-Soluble Polymers Using Asymmetrical Flow Field-Flow Fractionation

    Author : Bengt Wittgren; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; multi-angle light scattering; molar mass distribution; aggregation; size characterisation; Asymmetrical flow FFF; water-soluble polymers; polysaccharides; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

    Abstract : Size, as expressed by molar mass, radius of gyration or hydrodynamic radius, for example, is a fundamental parameter of polymers in solution. Thus, there is a strong need for the characterisation of both the size and shape of polymers, particularly of those utilised in various industrial applications. READ MORE

    Author : MAGNUS ARNELL; Ulf Jeppsson; Bengt Carlsson; Hans Bertil Wittgren; Diego Rosso; Industriell elektroteknik och automation; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; benchmarking; BSM; samrötning; energieffektivitet; växthusgasutsläpp; livscykelanalys; matematisk modellering; avloppsvattenrening; benchmarking; BSM; codigestion; energy efficiency; greenhouse gases; life cycle assessment; mathematical modelling; wastewater treatment; benchmarking;

    Abstract : As the knowledge about anthropogenic impacts of climate change has grown, the awareness of the contributions from treatment of wastewater has widened the scope for wastewater treatment plants (WWTPs). Not only shall ever stricter effluent constraints be met, but also energy efficiency be increased, greenhouse gases mitigated and resources recovered. READ MORE
