Oxidative–reductive photodecomposition of perfluorooctanoic acid in water

This article aims to elucidate on usefulness of vacuum ultraviolet (VUV) for photoreductive degradation of perfluorooctanoic acid (PFOA), a representative perfluorinated compound (PFC), in water for the first time. Bench-scale tests were conducted on oxidative and reductive (with aquated electron: eaq ) mineralization of PFOA using low-pressure UV (LPUV) lamps and potassium iodide. Unlike with ...

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

Photodecomposition and Phototoxicity of Natural Retinoids

Sunlight is a known human carcinogen. Many cosmetics contain retinoid-based compounds, such as retinyl palmitate (RP), either to protect the skin or to stimulate skin responses that will correct skin damaged by sunlight. However, little is known about the photodecomposition of some retinoids and the toxicity of these retinoids and their sunlight-induced photodecomposition products on skin. Thus...

On the Photodecomposition of C10N0

As its major removal process the photodissociat ion of a tmospheric C 1 0 N 0 2 in the ultraviolet is discussed. It has repeatedly been pointed out that significance should be at t r ibuted to the pathways of chlorine nitrate fo rmat ion and its destruction since this compound might be involved in the ozone depletion mechanism through both the C10x and N O x a tmospheric cycles. This communica ...
