1. 1. Sorption Microcalorimetry: Method Development and Applications

   Författare :Natalia Markova; Fysikalisk kemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; lyotropic phase transition; hydrate formation; crystallization; sorption enthalpy; sorption isotherm; water vapor; isothermal heat conduction calorimetry; sorption; Physical chemistry; Fysikalisk kemi;

   Sammanfattning : A double twin isothermal microcalorimeter has been designed and its performance has been tested experimentally. The calorimeter makes it possible to continuously and isothermally scan a solid sample in a broad range of relative vapor pressures at near-equilibrium conditions. LÄS MER

3. 2. Experimental studies of sorption and transport of moisture in cement based materials with supplementary cementitious materials

   Författare :Mahsa Saeidpour; Avdelningen för Byggnadsmaterial; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cement; Concrete; Moisture transport; Hysteresis; Supplementary cementitious materials; Water vapor sorption; Sorption isotherms; Anomalous sorption;

   Sammanfattning : Most deterioration processes in cement based materials are closely related to moisture sorption and moisture transport properties. Therefore, it is important to study these properties, both theoretically and practically. This work is an experimental investigation in this field. LÄS MER

4. 3. Transport and Sorption Phenomena in Concrete and Other Porous Media

   Författare :Björn Johannesson; Göran Fagerlund; Avdelningen för Byggnadsmaterial; []

   Sammanfattning : The work presented in this thesis is mainly focused on transport processes involved in service life predictions of concrete. Two papers and three reports deal with ion transport in pore solution of concrete. LÄS MER

5. 4. Equilibrium and Kinetic Batch Studies of Cadmium and Lead sorption using Low Cost Biosorbents

   Författare :Grace Bakyayita Kizito; Ann-Catrine Norrström; Robinah Kulabako; Mai Nalubega; Dan Berggren Kleja; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biosorbents; cadmium; chemisorption; isotherms; kinetics; lead;

   Sammanfattning : Agricultural wastes; Albizia coriaria, Coffea canephora, Cyperus papyrus, Erythrina abyssinica and Musa spp were evaluated for uptake of aqueous Cd2+ and Pb2+ ions in single- and binary-component solutions. Untreated, base-treated and peroxide-treated biomasses were employed in batch studies. LÄS MER

7. 5. Sludge-derived char : utilisation as a metal sorbent in dilute wastewaters

   Författare :Ida Sylwan; Eva Thorin; Lena Johansson Westholm; Konrad Koch; Mälardalens universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sorption; adsorption; sludge; biosolids; metal; wastewater treatment; sorption; adsorption; slam; metaller; avloppsvattenrening; Energy- and Environmental Engineering; energi- och miljöteknik;

   Sammanfattning : Metal concentrations in soil and water have increased since the Industrial Revolution, which may have negative health and environmental effects. Metal pollution occurs, for instance, in municipal wastewater, industrial wastewater, and stormwater. Concentrations are often low, due to dilution. A common technology for metal removal is sorption.
