Post-column photochemical reactions may be used to enhance the sensitivity or selectivity of detection in high-performance liquid chromatography (HPLC). Several new photochemical reaction detection schemes are discussed. Anthraquinones may be detected with extremely high selectivity based on a photocatalytic reaction in the presence of oxygen to produce hydrogen peroxide. The hydrogen peroxide is subsequently detected by the highly sensitive peroxyoxalate chemiluminescence reaction. Catalytic factors ranging from 40 to 70 are achieved for many quinone analytes. Use of an immobilized fluorophore and solid-bed reagent addition makes this detection scheme particularly easy to implement. In the absence of oxygen, quinones are photoreduced in the presence of certain hydrogen-atom-donating substrates to produce highly fluorescent dihydroquinones. Thus, quinone derivatives may be used as photochemical reagents for the detection of analytes such as aliphatic alcohols, ethers, aldehydes, and amines. This post-column photochemical reaction is particularly useful for the detection of compounds having no chromophore such as saccharides and steroids. The fast reaction of singlet oxygen with either 2,5-diphenylfuran or 2,5-dimethylfuran forms the basis of a photochemical amplifier for UV-absorbing compounds. This method is photocatalytic and leads to improved detection limits in UV absorption by factors of one to two orders of magnitude. This photochemical reaction allows non-fluorescent compounds to be detected in HPLC using a UV detector with sensitivities rivaling those of fluorescence detection (typically 1 to 10 pg of compound).

Accelerated Aging: Photochemical and Thermal Aspects represents the culmination of more than 40 years of research by noted scientist Robert L. Feller. The book focuses on the long-term performance of materials such as wool, dyes, and organic compounds; their resistance to change when exposed to environmental factors such as oxygen, ozone, moisture, heat, and light; and their physical durability with handling and use over time. Processes of deterioration are discussed based on speeded-up laboratory studies designed to clarify the chemical reactions involved and their physical consequences.

Download Heterogeneous Photocatalysis Using Inorganic Semiconductor Solids Book in PDF, ePub and Kindle
This book underscores the essential principles of photocatalysis and provides an update on its scientific foundations, research advances, and current opinions, and interpretations. It consists of an introduction to the concepts that form the backbone of photocatalysis, from the principles of solid-state chemistry and physics to the role of reactive oxidizing species. Having recognised the organic link with chemical kinetics, part of the book describes kinetic concepts as they apply to photocatalysis. The dependence of rate on the reaction conditions and parameters is detailed, the retrospective and prospective aspects of the mechanism of photocatalysis are highlighted, and the adsorption models, photocatalytic rate expressions, and kinetic disguises are examined. This book also discusses the structure, property, and activity relationship of prototypical semiconductor photocatalysts and reviews how to extend their spectral absorption to the visible region to enable the effective use of visible solar spectrum. Lastly, it presents strategies for deriving substantially improved photoactivity from semiconductor materials to support the latest applications and potential trends.
