| Abstract: | Diatomite was calcined and leached by sulfuric acid to remove impurity. The crude diutomite and purified diatomite was characterized by SEM and XPS. The adsorption capability of the diatomite to Rhodamine B solution was studied. The test results showed that the specific surface of the diatomite is enhanced when the crude diatomitc was purified and the adsorption of the purified diatomite is improved effectively. The adsorption data ofRhodamine B by the crude diatomite and purified diatomite fitted well to the Freundlich isotherm equation. |

| Keywords: | diatomite purification adsorption specific surface |
