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.

荞麦微孔淀粉对亚甲基蓝的吸附热力学遵循Langmuir直线吸附方程的单分子层吸附规律，碱性条件的单分子层饱和吸附量比酸性条件高2.9倍；pH值从4.8增大至10.8，吸附热负值增大，吸附为放热的自发过程，且在pH10.8时吸附所受到的静电斥力小，吸附更容易进行。
