Intrinsic viscosity and conformational parameters of xanthan in aqueous solutions: Salt addition effect

- A new model of Wolf was applied for accurate evaluation of intrinsic viscosity.
- Effect of monovalent counterions on conformational parameters of xanthan is reported.
- Types of interactions in solution are discussed as a function of salt concentration.
- Stiffness parameter is 5.45 × 10−3, suggesting a rigid conformation, similar to DNA.
