Kinetic Studies of Fenton Oxidation Reaction by UV-VIS Spectroscopy

Coupled UV−Vis/FT−NIR Spectroscopy for Kinetic Analysis of Multiple Reaction Steps in Polymerizations

We couple UV−vis and FT−NIR spectroscopy for the real-time monitoring of polymerization reactions, allowing the simultaneous tracking of the rates of light absorption and initiator/monomer consumption, from which dynamic and previously difficult-to-measure parameters are calculated: quantum yields of initiator consumption, initiation and polymerization, photosensitivity, and residual content of...

UV-VIS spectroscopy of 2,4,6-trinitrotoluene-hydroxide reaction.

Contamination of groundwater, surface water and soil by explosives has occurred at military sites throughout the world as a result of manufacture of explosive compounds, assembly of munitions, and deployment of explosives containing devices. Due to the adverse effects of explosives on humans and other natural receptors, a low cost means of decontaminating these areas of contamination is needed....

UV-Vis spectroscopy of stardust

NASA’s Stardust mission flew through the coma of comet Wild 2 in January 2004, capturing dust grains as it did so. The grains were returned safely to Earth in January 2006, and are in the process of being distributed to investigators. As members of the Spectroscopy Preliminary Examination Team, we are preparing to analyse Stardust grains. Our contribution is to measure the spectrum of the grain...

Significance of UV-Vis spectroscopy in in vitro release studies

SUSPENSION STABILITY OF TITANIA NANOPARTICLES STUDIED BY UV-VIS SPECTROSCOPY METHOD

Ultraviolet–Visible (UV–Vis) spectroscopy was used, in the current investigation, to explore the dispersion and stability of titania nanoparticles in an aqueous media with different types of dispersants. Hydrochloric and nitric acids as well as ammonia were used to determine the stability of the suspension in the acidic region (pH=2.5) and basic area (pH=9.5), respectively. In addition, for mea...
