Synthesis and Characterization of Coconut Pith Char Adsorbents for Carbon Dioxide Capture

The purpose of this study is to investigate the performance of coconut pith char as an adsorbent for capturing anthropogenic CO2 gas before it is emitted to the atmosphere. Coconut pith chars were successfully synthesized and characterized as a potential CO2 adsorbent. Coconut pith char was used...
