EDTA- and DTPA-functionalized silica gel and chitosan adsorbents for the removal of heavy metals from aqueous solutions
(Lappeenranta University of TechnologyLaboratory of Green Chemistry, 2011-08-05)
Adsorbents functionalized with chelating agents are effective in removal of heavy metals from aqueous solutions. Important properties of such adsorbents are high binding affinity as well as regenerability. In this study, ...
Possibilities and challenges of longitudinal studies in operations management
(Lappeenranta University of Technology, 2011-12-19)
Longitudinal studies are quite rare in the area of Operations Management. One reason might
be the time needed to conduct such studies, and then the lack of experience and real-life
examples and results.
The aim of the ...
Polymer surface modification by atomic layer deposition
(Lappeenranta University of Technology, 2011-12-19)
Current industrial atomic layer deposition (ALD) processes are almost wholly confined to glass or silicon substrates. For many industrial applications, deposition on polymer substrates will be necessary. Current deposition ...
Identification of extractives and polysaccharides as foulants in membrane filtration of pulp and paper mill effluents
(Lappeenranta University of Technology, 2011-12-18)
The search for new renewable materials has intensified in recent years. Pulp and paper mill process streams contain a number of potential compounds which could be used in biofuel production and as raw materials in the ...
