Investigation of the effect of NaCl on ultrasonic xanthan degradation

Ali Özhan Akyüz


Xanthan presents wide applicability in pharmaceutical, cosmetic and food industries because of low cost and different physicochemical characteristics in aqueous solutions. In this study ultrasonic degradation of Xanthan is investigated in NaCl solutions. The solution is changed by varying NaCl concentration between 0.5-10 mM and ultrasound frequency-intensity, xanthan concentration, temperature kept constant. Degradation kinetics was monitored by viscometry and is found to depend on NaCl concentration in solution.
