Highly porous calcium hydroxyapatite-based composites for air pollution control

Abstract : The control of emission gas from incinerators appears as a key issue for the improvement of the incineration technology. In this paper, we developed new sorbent materials based on calcium hydroxyapatite (Ca-HA) matrix. Using gelatine and bio-glass as porous and structural agents, which are largely available and have reasonable costs, powder of Ca-HA could be easily formulated into desired morphologies. As an example, a Ca-HA based accumulator having good porosity and mechanical stability was obtained by mixing Ca-HA powder with gelatine, bio-glass and water, followed by molding, then calcination steps. This accumulator showed an interesting capacity for the collection and tracing of Cd used as single model heavy metal in gas phase.
