چکیده
|
This paper discusses the effects of uv light exposure on citrus paradisi (grapefruit) peel in terms of naringin and tinuvin 622 (a commercial stabilizer) compounds. this study aimed to develop a plant extract with the necessary properties to protect polystyrene from sunlight. polystyrene films containing a low concentration of naringin were prepared, and tinuvin 622, a commercial uv light stabilizer, irradiated the polystyrene sheets for 300 hours. following irradiation, the study examined the infrared spectrum of polystyrene, weight loss, molecular weight reduction, and changes in surface morphology. naringin and tinuvin 622 significantly reduced the photodegradation of polystyrene films, acting as photostabilizers when compared to blank films.
