Photolyse du complexe Tris(éthylxanthato) Chrome (III) dans le DMSO
ISBN: 9786203270242 / Francuski / Miękka / 92 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Dans le présent travail, nous avons préparé du tris(alkylxanthato)chrome(III) et avons voulu étudier la photochimie de ces complexes dans le diméthyl sulfoxyde. Ces complexes pourraient être utiles dans de nombreuses applications. De plus, le chélate de métal avec des métaux à haut degré d'oxydation est actif dans l'amélioration de la photodégradation du plastique et pourrait donc servir de photocatalyseur pour traiter le problème de la pollution des déchets plastiques. L'effet du nombre de groupes méthyle dans ces complexes a également été étudié. Ces travaux portent...

Photolyse von Tris(ethylxanthato)-Chrom(III)-Komplex in DMSO
ISBN: 9786203270228 / Miękka / 92 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. In der vorliegenden Arbeit haben wir Tris(alkylxanthato)chrom(III) hergestellt und beabsichtigt, die Photochemie dieser Komplexe in Dimethylsulfoxid zu untersuchen. Diese Komplexe könnten in vielen Anwendungen nützlich sein. Darüber hinaus sind Metallchelate mit Metallen in hohen Oxidationsstufen aktiv in der Verbesserung des Photodegrades von Kunststoffen und könnten daher als Photokatalysatoren zur Behandlung des Problems der Plastikmüllverschmutzung dienen. Der Effekt der Anzahl von Methylgruppen in diesen Komplexen wurde ebenfalls untersucht. Diese Arbeit beschäftigt sich auch mit...

Photolysis of Tris(ethylxanthato) Chromium (III) complex in DMSO
ISBN: 9783844331714 / Angielski / Miękka / 2011 / 92 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. In the present work we prepared tris(alkylxanthato)chromium(III) and intended to study the photochemistry of these complexes in dimethyl sulfoxide. These complexes might be useful in many applications. Moreover, metal chelate with metals at high oxidation state is active in the enhancement of photodegradation of plastic and therefore, might serve as photocatalyst to treat the plastic waste pollution problem. The effect of number of methyl group in these complexes has been also studied. This work also deals with the photochemical reaction and determination of quantum yields and reactivity...

High Performance Liquid Chromatography
ISBN: 9783659170461 / Angielski / Miękka / 2012 / 76 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. New stationary phases for high performance liquid chromatography has been prepared by the reaction of Bromophenol blue salt solution with Amberlite CG-400 (Cl-) resin . The stability of the new attached functional group on the resin was studied against different solvents such as benzene, ethanol, acetonitrile, acetone, methanol, chloroform, and petroleum ether as well as NaOH and HCl solutions. The new prepared resin was found stable and no depletion of the Bromophenol blue moity from the resin was noticed with the above materials .The FTIR analysis has configured the attachment of...

Photochemistry
ISBN: 9783659513008 / Angielski / Miękka / 2014 / 88 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. This work was made to study the photochemistry of riboflavin and the kinetics of riboflavin degradation after exposure to UV-Vis light phosphate buffer solution at different pH interval (2-10) with the same concentration (5x10-5M ) was studied by the of UV-Vis spectrophotoscopy analyses, it showed that degradation increase as pH increase from pH (2-7)where the lumichrome a photoderivative forms in the acidic medium. a maximum degradation occurs at neutral pH (7). Then it began to decrease from pH (7-10). Where the lumiflavine (a photoderivative occurs at basic media) formed. We also...
