From the microscope images listed a

From the microscope images listed above, it can be seen that the corn starch particles are round, elliptical or polygonal, with a clear outline and a dispersed and isolated state. , The particles have different shapes and sizes, there are obvious traces of connection between the particles in the mesh part, the starch particles no longer have sharp edges and corners, there are signs of wrapping and winding on the outer surface, the irregularity increases, which is beneficial to bridging flocculation and net catching The sweeping effect may be the result of modification, and adding coagulant chitosan, activated carbon, kaolin to it indicates that it has adsorption capacity and may have strong adsorption capacity.
