Viscosity and Structure of KDP Aqueous Solution

Article Preview

Abstract:

The corresponding relationship among KDP solution viscosity, concentration and temperature was researched respectively, to explore the empirical formula of the viscosity of KDP solution. The experimental results showed that the viscosity increased with the increase of ionic strength and reciprocal of temperature. Viscosity had exponent relation to ionic strength and reciprocal of temperature, fitting in well with the empirical formula: See formula in paper. The X-ray diffraction analysis showed that with the increasing amount of KDP, a new peak emerging in the diffraction spectrum accorded with molecular structure of KDP crystals, and some peaks which accorded with the structural features of water molecules gradually disappeared. It showed that with the increase of the amount of KDP, the internal structure of KDP solution had changed.
