Abstract

CaO samples prepared from calcining the powdered waste shells at 1300ฐC for 4 h were tested the efficiency of humidity adsorption. The samples were characterized via X-ray diffraction (XRD) and Fourier transform infrared analysis (FT-IR) to identify the characteristic of CaO after humidity adsorption test. The results indicate that duck eggshells are highest capable of humidity adsorption while hydration rate of chicken eggshells is rather equal to that of cockle shells, and lowest hydration rate was found with sample prepared from Mussel shells. Therefore, we can conclude that the waste shells are suitable to be use as humidity adsorbent for commercial in the future. ฉ (2012) Trans Tech Publications.
