dc.description.abstract Sudan produces about 50% of the global demand for Gum Arabic and of Talha Gum (acacia seyal) . However, the product is exported in a raw form or with minimum treatment for package purposes such as size reduction. This research work is aimed to decolourize Talha Gum to improve its quality. The experimental set up consists of adsorption column made of Perspex. The adsorption media is activated charcoal of 500μm in size. The adsorption bed is 15cm in depth. The experiment was conducted for wide range of Talha Gum concentrations (5.5 -55 g/l). The transmittance, pH, TDS and viscosity were measured for raw and treated samples. The result showed that the colour has changed from pink to colourless transparent. The transmittance (%) has improved from 137 at wave length of 800nm to 146.1 at the same wave length for Talha Gum concentration of 55g/l (as maximum concentration). The treated solution becomes also less acidic after treatment and there was no significant change in its viscosity en_US
