Study of Semiconductor Photocatalysed Oxidation of Indispensable Nutrient Vitamin C

Dr. Pushkar Raj Meena [3]

Abstract: Semiconductor photocatalytic process has been widely applied as a ?green? technology in treating environmental contaminants, such as the removal of the indoor organic pollutants and degradation of the soluble hazardous material in waste water. TiO2 is the most frequently used photo catalyst because of its photo stability and low cost, combined with its biological and chemical inertness and resistant to photo and chemical corrosion. It is known under aqueous conditions, organic contaminants in wasted water can be degraded into CO2 and H2O, whereas under dry organic solvent or controlled pH, irradiation time, by using visible or UV light etc; the organic compounds may also be selectively oxidized into fine chemical products rather than complete mineralization. Ascorbic acid (vitamin C) is an essential micronutrient that performs important metabolic functions. It is sensitive to air and light and is degraded by chemical and photochemical oxidation. Ascorbic acid is an ingredient of anti - aging cosmetic products and exerts several functions on the skin as collagen synthesis, depigmentation, and antioxidant activity. As an antioxidant it protects skin by neutralizing reactive oxygen species generated on exposure to sunlight. In biological systems it reduces both oxygen - and nitrogen - based free radicals and thus delays the aging process. In view of the instability of ascorbic acid in skin care formulations, it is often used in combination with another redox partner such as alpha - tocopherol (vitamin E) to retard its oxidation. The methods of testing the photostability of dermal preparations have been described by Thoma and Spilgies. The produced photo - product has been isolated as its derivatives and then analyzed them by appropriate spectral or other suitable methods. Hence, this part of reported work may help to arouse the interdisciplinary interest for chemists as well as pharmacists.
