The Present Situation and Development of Diatomite
The diatomite is characteristic of Porosity, low density, high superficial area, good adsorbability, acid resistant, alkali resistance, insulation and rich reserves. As a result, the diatomite is widely used in many industrial sector as a kind of new adsorption material. The character of diatomite including chemical components and surface characteristics is briefly introduced, then describes synthetically the method of diatomite modified by the polymer such as polyaniline and polyethyleneimine. The recent research progress of the method of diatomite modified based on the different wastewater and their absorbing dyes, heavy ions and nonpo-lar aromatic in wastewater are summarized. The future development trends as new adsorption materialare also introduced in brief.
