Research Abstract |
Commercial hydrotalcite calcined at 500℃ showed maximum phosphorous removal ratio. On the other hand, hydrotalcite vibro-milled for 6hrs under a dry condition showed maximum removal ratio of phosphorous on heating at 250℃. Consolidated bodies with high phosphorous removal and recovery efficiencies were obtained by carbonation of wet powder mixture of hydrotalcite and wollastonite at 80℃ for 3hrs under 0.4MPa CO_2 pressure followed by calcination at 500℃. These consolidated bodies showed enough durability against repeated phosphorous removal, ion exchange and heat treatment.
