Diatomite Modification and its Adsorption of Heavy Metal ...

Diatomite plays a very important role in sewage adsorption and especially has vast prospect in adsorbing heavy metal ions. The paper, on the basis of domestic and overseas literatures concerning diatomite, summarizes the modification methods of diatomite and adsorption research of heavy metal ions. Besides, it also forecasts the prospect of using diatomite to specifically adsorb heavy metal ion.

Removal of noxious heavy metal ions (e.g. Pb(II)) by surface adsorption of minerals (e.g. diatomite) is an important means in the environmental aqueous pollution control. Thus, it is very essential to understand the surface adsorptive behavior and mechanism. In this work, the Pb(II) apparent surface complexation reaction equilibrium constants on the calcined diatomite and distributions of Pb ...

 · Diatomite and manganese oxide modified-diatomite (Mn-diatomite) were tested for heavy metal removal from wastewater. Impregnating the diatomite surface with 0.38 g g −1 of manganese oxide gave a 2.4-fold increase in the adsorbent surface area. Equilibrium studies demonstrated that diatomite has a higher removal capacity for Pb 2+, Cu 2+ and Cd 2+ from water than untreated diatomite.
