Adsorption of some Starches on Particles of Spar Minerals

Abstract

The adsorption mechanism of starch at mineral-solution interface was investigated for the system, water soluble potato starchspar minerals. Adsorption isotherms of the Langmuir type and the high occupation area of starch molecules suggested relatively flat orientation of starch molecules on the mineral surface. Mineral solubility, crystal lattice structure, associated mineral impurities and the ionic composition of the pulp were shown to control the adsorption process.
