Název v původním jazyce
Kinetics study of photocatalytic oxygen indicator reactions
Popis výsledku v původním jazyce
The indicators are comprised of TiO2, Remazol Brilliant Blue R, glycerol, and polymer. Two different polymer matrices, poly(vinyl acetate) (PVAC) or (carboxy)methyl cellulose (CMC) were used. The indicators were printed on a plastic foil and covered with a UV curable coating. Data for the kinetic study of photocatalytic reduction and oxidation were gathered with reflectance spectrophotometer and the kinetic analysis was based on the change of the indicator's optical density. Both indicators were successfully activated with UVA and both detected oxygen. The rate of oxidation depended on percentual oxygen concentration, increasing with increasing oxygen concentration. The PVAC based indicator was much quicker to detect oxygen than its CMC counterpart, the former having a color change response to oxygen that is easily detected by naked eye in just one minute.
