Enhancing extraction performance of organophosphorus flame retardants in water samples using titanium hierarchical porous silica materials as sorbent…
2021
Abstract A sorbent for the extraction of organophosphorus flame retardants has been proposed, based on UVM-7 (University of Valencia Materials) mesoporous silica doped with titanium. Designed cartridges have been applied to the extraction and preconcentration of flame retardants in water samples, followed by gas chromatography coupled to a mass spectrometry detector. Firstly, UVM-7 materials with different contents of titanium were synthesized and characterized by several techniques, thus confirming the proper mesoporous architecture. The potential of these materials was assessed in comparison with their morphological properties, resulting Ti50-UVM-7 the best solid phase. Several extraction…
Preconcentration of emerging contaminants in environmental water samples by using silica supported Fe3O4 magnetic nanoparticles for improving mass de…
2011
A magnetic material based on Fe(3)O(4) magnetic nanoparticles incorporated in a silica matrix by using a sol-gel procedure has been used to extract and preconcentrate emerging contaminants such as acetylsalicylic acid, acetaminophen, diclofenac and ibuprofen from environmental water samples prior to the analysis with Capillary LC-MS. The use of the proposed silica supported Fe(3)O(4) magnetic nanoparticles enables surfactant free extracts for the analysis with MS detection without interferences in the ionisation step. Under the optimum conditions, we demonstrated the reusability of the magnetic sorbent material during 20 uses without loss in the extraction efficiency. In addition, no cleanu…
Kropp i bevegelse i bildeboka : Känner du Pippi Långstrump?
2011
In Astrid Lindgren’s authorship, there are many bodies in motion, and one of her most movable and energetic characters is Pippi Longstocking. In the illustrated novels about Pippi (Lindgren and Nyman 1945, 1946, and 1948) there are relatively few pictures, and as a result, Lindgren’s words carry most of the story. In the novels, her words have a greater functional load (Kress 2003, 46 ) than Nyman’s pictures. Naturally then, the words convey most of the information about Pippi and the other characters’ movements. But how does the portrayal of bodies in motion change when Pippi is portrayed in picturebooks where the pictures have a lot more space, ie, a greater functi…
