The Research of Scrub on the Performance of Diatomite

Abstract:

The internal structure of diatomite has nanometer-level micropore and fine adsorptivity, but internal porosities of crude diatomite were blocked by impurities which should be removed. The characteristics of original and scrubbed diatomite were compared by SEM,TEM,specific surface area analyzer and FT-IR. The test results indicated that the SiO₂ content of scrubbed diatomite increased from 80.61% to 89.56%, specific surface area increased from 7.96 m²/g to 14.39 m²/g and the external activity improved, and the adsorption of performance of scrubbed diatomite was better than that of original diatomite.
