This document delves into the differences between soft and hard carbon domains, elucidates the mechanisms controlling hydrophobic organic compound (HOC) sorption by soil organic matters (SOMs), and outlines key experimental findings. It details the objectives behind the experiment, focusing on sorption and displacement methodologies. The study further analyzes sorption results, particularly N2 in various soils, composition variations, pyrene sorption, and displacement coefficients. Finally, it summarizes the overarching outcomes and suggests future research directions to build on these findings.
