The Effect of Ultrasonication in Molecular Weight Parameters of Sodium Alginate Solution

Abstract

Abstract: In the ultrasonication the pHof the sodium alginate solution was stable,its temperature increased,and its apparent intrinsic viscosity decreased, and a change of three steps of decreasing, raising, and redecreasing occured in apparent average molecular weight of the sodium alginate. After the ultrasonication the apparent intrinsic viscosity and the apparent average molecular weight raised slightly we inferred that the conformation of the sodium alginate was changed under the condition.
