Study of oxide nanostructure catalysts on polypropylene carrying agents for the removal of organic contaminants from water

Superficial acid-base properties of polymer fibres

“…Thus, the results indicate that all the PFM due to the presence of carboxyl groups on the surfaces, enable modification of their surfaces with metal nanoparticles, thereby giving them unique properties, e.g., photocatalytic and bactericidal. The findings agree well with earlier results [20][21][22].…”

Photoinduced Bactericidal Activity of Titanium Dioxide Nanoparticles Attached to the Surface of Polypropylene Fibers

“…For the production the sample 1 we added 2 ml of 12 % aqueous TiCl 3 to 50 ml of distilled water, and then NH 4 OH to pH 3.7 constantly stirring. Polypropylene fiber content of 1 g was placed in a container with prepared gel of the hydrolysis products of starting salts in it, kept for 15 minutes at room temperature and then took out from the gel fiber, squeezed to remove excess solution for dehydration and consolidation nanoparticles, heated in microwave with 650 W output and frequency of 2.45 GHz for 2-3 min [4]. For the production the sample 2 polypropylene fiber content of 1 g was placed in a container with 50 ml of 12 % aqueous TiCl 3 , kept for 15 minutes at room temperature and then took out from aqueous TiCl 3 , squeezed to remove excess solution for dehydration and consolidation nanoparticles, heated in microwave with 650 W output and frequency of 2.45 GHz for 5 min.…”

Acid-base properties of surface of polymeric fibrous materials

“…Хотя энергия водородной связи невелика, недиссоциированные карбоксильные группы способствуют предварительному закреплению на поверхности волокон металлосодержащих наночастиц. Следовательно, поверхность ПВМ может быть модифицирована металлическими наночастицами, с их последующим закреплением, например, в поле СВЧ излучения, как в работах [11,12].…”
