Investigation some of Physical Properties of Irradiated Sunflower Oil by Nd: YAG Laser (1064 nm)

Abstract

In this research the effect of continuous Nd: YAG laser on sunflower oil has been investigated. Sunflower oil samples irradiated by continuous Nd: YAG laser 1064 nm wavelength and different output powers (0, 10, 30 and 60) W for time five minutes for all samples, then the refractive index, viscosity, pH value and saponifaction value was determined for each sample. The results reveals a significant changes of increase and decrease in the physical properties (refractive index and viscosity) of the oil due to laser irradiation, it also results in significant changes of increase and decrease in the chemical properties; (pH value and saponifaction value) of the oil.
