Quantitative Optical Properties of Acacia tortilis var. raddiana Gum using Ultra Violet Visible “UV- VI” Spectrophotometer

n this work, three samples of Acacia tortilis var.raddiana gum were collected from different locations in Sudan: (Wd-Mahala Forest ) Khartoum, (SharqElneel) Khartoum and (Tayba forest) in Gezira State. UV-VS mini 1240 spectrophotometer was used to study the quantitative optical properties (absorbance, transmission, reflection and absorption coefficient). The samples were prepare in six different weight (0.3, 0.5, 0.7, 0.10, 0.15 and 0.20g) and dissolved in distil water; hence the absorption of Acacia tortilis var. raddiana gum was recorded. The result at wavelength (200 – 315) nm show that, the absorbance (2.427- 3.771) a.u, the absorption coefficient (5.568 –8.735) cm-1, the transmission (0.69 –0. 961) at wave length (318-500) nm, and reflection (0.17-0.204). These results indicate that, the (Acacia tortilis var. raddiana) gum is an excellent material can be used in different devices and manufacturing of goggles and filters as they prevent the transmission of UV and allows the passage of visible light.
