Removal of Elemental Mercury by Coconut Pith Char Adsorbents. (2016) - Johari, Khairiraihanna
Abstract: Coconut pith (CP), which is abundantly available and cheap, has the potential of being used as low-cost adsorbents for elemental mercury removal. In this study, the preparation of chars was carried out through the carbonization of CP at three different environment conditions: (a) open reactor under nitrogen flow; (b) closed reactor under nitrogen environment; and (c) closed reactor under ambient environment; at the temperature of 700 °C. The results show that the chemical, physical, morphological and spectral properties of the adsorbents greatly influenced by the environment of carbonization used. The highest Hg o adsorption capacity was observed for CCA700 (2395.98 μg/g), followed by CCN700 (2052.49 μg/g), and CFN700 (1416.92 μg/g). These results demonstrated that coconut pith derived chars could be potential as low-cost adsorbent alternatives for the removal of elemental mercury in gas streams.
