  1. 11. Extraction of Metal Values Thermodynamics of Electrolyte Solutions and Molten Salts Extraction Process

    University dissertation from Stockholm : KTH

    Author : Xinlei Ge; KTH.; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrolyte solutions; activity coefficient; osmotic coefficient; freezing point depression; boiling point elevation; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap;

    Abstract : Over the past centuries, a number of process routes for extraction of metal values from an ore or other resources have been developed. These can generally be classifiedinto pyrometallurgical, hydrometallurgical or electrometallurgical routes. READ MORE

  2. 12. Ozone chemistry in aqueous solution ozone decomposition and stabilisation

    University dissertation from Stockholm : KTH

    Author : Margareta Eriksson; KTH.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi; NATURAL SCIENCES Chemistry; NATURVETENSKAP Kemi;

    Abstract : Ozone is used in many applications in the industry as an oxidising agent for example for bleaching and sterilisation. The decomposition of ozone in aqueous solutions is complex, and is affected by many properties such as, pH, temperature and substances present in the water. READ MORE

  3. 13. Association Phenomena in Aqueous Solutions of Surfactants and Hydrophobically Modified Polymers

    University dissertation from Physical Chemistry 1, Lund University

    Author : Susanne Nilsson; Lunds universitet.; Lund University.; [1999]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; self-diffusion; rheology; cellulose ethers; associating polymers; polymer-surfactant interactions; polymer network; Fysikalisk kemi; Physical chemistry;

    Abstract : Interactions between ionic surfactants (sodium dodecyl sulfate and dodecyltrimethylammonium chloride) and nonionic polymers ((hydroxyethyl)cellulose, ethyl(hydroxyethyl)cellulose and their hydrophobically modified analogous) have been studied by means of rheology, pulsed field gradient nuclear magnetic resonance (PFG NMR), time-resolved fluorescence quenching (TRFQ), dynamic light scattering (DLS) and cryo-transmission electron microscopy (cryo-TEM). In all experiments surfactants have been added in various amounts to polymer solutions at fixed concentrations. READ MORE

  4. 14. Surface reactivity, stability, and mobility of metal nanoparticles in aqueous solutions : Influence of natural organic matter and implications on particle dispersion preparation

    University dissertation from Stockholm : Kungliga Tekniska högskolan

    Author : Sulena Pradhan; KTH.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nanoparticles; freshwater; di-hydroxybenzoic acid; humic acid; copper; aluminium; manganese; dissolution; agglomeration; stability; complexation; Kemi; Chemistry;

    Abstract : The growing development of nanotechnology has resulted in an increased use of nanoparticles (NPs) in various applications ranging from medicine, military, to daily consumer products. There is a concern that NPs can be dispersed into the environment in various ways, for example to air and water during manufacture, use, incineration or recycling of products and thus pose a risk to health and the environment.
