Biochar functional groups
WebBiochar (BC) is one of the many soil amendments. Because of its special structure and property, such as huge specific surface area, its richness in oxygen-containing functional groups, and a large number of surface charges, BC could be an alternative absorbent. WebJan 3, 2024 · 2.2 Chemical adsorption. Different from physical adsorption, chemical adsorption is mainly based on specific functional groups on the surface of biochar [53, 54].The way and the degree to which different functional groups interact with CO 2 molecules varies [55, 56].Furthermore, chemical adsorption is often the result of the …
