The magnetite with a mean diameter of 8nm was prepared by chemical coprecipitation methods. By the addition of nonionized oleic acid to the suspension of magnetite in solution during precipitation, the magnetite nanoparticles were coated with a double surfactant layer. A gel-like precipitated precursor is then formed because of the hydrophobic interaction among those coated units. By transferring of this precursor to an organic solvent, the surfactant double layer on Fe〓O〓 nanoparticles reduces to one; however, it still remains as a double layer by transferring to an alkaline aqueous solution. Both these cases give in stable colloids of superparamagnetic Fe〓O〓 nanoparticles.

The thermodynamics about the buckwheat microporous starch absorbing the methylene blue follows the monolayer absorption rule of the Langmuir equation. The alkalinity condition monolayer saturated adsorption is 2.9 times higher than acidic condition. When pH value rose from 4.8 to 10.8, the negative value of absorption heats increased, absorption was spontaneous exothermic process, and that was easier to carry on at pH10.8 due to the slight adsorption electrostatic repulsion.
