Abstract: The reaction equation of the starch and micro-fine hematite has been put forward combining with the collision theory. After analyzing the equation and test data,the reaction order of the starch and fine hematite particle obtained by integration method and half-life method can be approximately seen as the first level. It lays the foundation for research on adsorbing rate equation of this system. 

Key words: Micro-fine hematite, Kinetics, Adsorption
