Abstract

To clarify the effect of activators on adsorption characteristics of the carbon-ceramics porous (CCP) materials prepared from industrial wastes, we investigated the adsorption properties of methylene blue (MB) cations to CCP materials synthesized with various activators added. The CCP material activated with K₂CO₃, KOH, and NaOH exhibited higher absorbability of MB than the CCP without activator. This result indicates that carbon component in the specimen can be activated during calcination at 850°C for 1 hours.
