Removal of drugs in aqueous systens by photoassisted degradation

2005

Aqueous solutions of tetracycline, lincomycin and ranitidine were irradiated with UV light in homogeneous and heterogeneous systems. Two commercial polycrystalline TiO2 powders (Degussa P25 and Merck) were used as photocatalysts. After 5A h, an appreciable photolytic degradation of tetracycline and ranitidine was observed while the degradation of lincomycin was noticeably lower. As far as the mineralization is concerned, a small decrease of the TOC values was measured in the case of tetracycline whereas negligible variations were found for lincomycin or ranitidine. The presence of the photocatalysts greatly enhanced the degradation rates of the drugs with respect to those observed during th…

Photocatalytic formation of H2 and value-added chemicals in aqueous glucose (Pt)-TiO2 suspension

2016

Abstract Commercial and home prepared bare and Pt-supported TiO2 samples were used as the photocatalysts for the aqueous photo-conversion of glucose at ambient pressure and temperature. Aerobic and anaerobic conditions were used to study the products of glucose degradation both in the liquid (arabinose, erythrose, gluconic acid, glucaric acid, fructose and formic acid) and gaseous (H2 and CO2) phases. The distribution of these molecules was different in the presence of the various powders, depending on the structural and physico-chemical properties of the materials, and Pt resulted essential for the anaerobic production of H2. The home prepared samples resulted more active than the commerci…

Constitutional Perspective of the Guarantees of Application of Artificial Intelligence: the Inescapable Protection of Fundamental Rights

2020

espanolLa Inteligencia Artificial tiene un innegable efecto en la sociedad actual, por lo que su estudio respecto de sus efectos juridicos deviene necesario. Y, en consecuencia, el modo en que se ven afectados los derechos fundamentales tiene especial importancia. De ahi que en el presente trabajo se estudie la influencia de los algoritmos en la determinacion de las resoluciones judi-ciales, sobre todo desde el punto de vista de como afectaria esta cuestion al derecho a la tutela judicial efectiva, reconocida como derecho fundamental en el articulo 24 de la Constitucion espanola. EnglishArtificial Intelligence has an undeniable effect on today’s society, so its study regarding its legal eff…

Interpretācija kā mākslas darba nosacījums: Hansa Georga Gadamera un Artūra Danto teoriju salīdzinājums

2021

Bakalaura darba mērķis ir pierādīt, ka atšķirības Artūra Kolmena Danto un Hansa Georga Gadamera mākslas teorijās izriet no atšķirīga interpretācijas jēdziena traktējuma. Pirmajās divās nodaļās uzrādīšu to, kā interpretācija saistās ar mākslu katras teorijas ietvaros, bet trešajā nodaļā no interpretācijas jēdziena skatupunkta salīdzināšu līdzīgos un atšķirīgos aspektus abās pieejās. Kā galvenos saskares punktus starp abiem domātājiem identificēju: (1) Georga Vilhelma Frīdriha Hēgeļa ideju turpināšanu un iestrādāšanu savās teorijās, (2) klasiskās un modernās mākslas pretnostatījuma pārvarēšanu, savienojot abu veidu mākslas vienā izpratnes shēmā, (3) interpretācijas izvirzīšanu par galveno nos…

Comparison between catalytic and catalytic photo-assisted propene hydration by using supported heteropolyacid

2012

Abstract Hybrid materials have been prepared by impregnation of the heteropolyacid H 3 PW 12 O 40 on commercial TiO 2 . The polyoxometalates (POM) amount deposited was 15, 30, 50 and 70% with respect to the weight of the TiO 2 support. Moreover two samples containing a POM amount of 15, and 50% with respect to the weight of SiO 2 were also prepared for the sake of comparison. All prepared samples were efficient catalysts for the hydration of propene to 2-propanol in gas–solid regime at atmospheric pressure and at temperatures ranging between 50 and 85 °C. The study carried out on the hybrid TiO 2 based materials evidenced that, as far as the catalytic activity is concerned, exists an optimu…
