PhysicochemicalCharacterization of Gamma Irradiated Acacia seyalGum

Abstract

The effects of A. seyalvarseyal gum aqueous solutions varying gamma radiation doses (10, 30 and 50 KGy) on some physicochemical properties of. The crude and gamma irradiated samples were characterized usingpH measurements,specific optical rotation, intrinsic viscosity andFTIR spectroscopy.The resultsshow that,the pH values of the irradiated samples were decreased with the increase in radiation dose regardless of the gum concentration.the optical rotation of the crude and gamma irradiated A.seyal gum samples does not show specific trend with increase in radiation doses. intrinsic viscosities of the gamma-irradiated A. seyal gumsamples have shown interesting trend with regard to gum concentration and gamma radiation doses.FinallyFTIR spectra showed slight differences between raw and γ-irradiated samples.
