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 …

Upon death of the organism, these siliceous elements become sedimentary particles in a diatomite deposit. The intricate structure of diatom frustules, and packing of the myriad diatom shapes into rock-forming sedimentary layers, gives diatomite deposits properties that are useful in many industrial and commercial applications.
