Activated carbon from biochar: Influence of its physicochemical properties on the sorption characteristics of phenanthrene

BIORESOURCE TECHNOLOGY, 149, 383–389.

By: J. Park n, I. Hung *, Z. Gan *, O. Rojas n, K. Lim * & S. Park n 

author keywords: Biochar; Solid-state NMR; Activation Activated biochar; Phenanthrene adsorption
TL;DR: The relationship between physicochemical properties of biochar-based activated carbons and its adsorption was investigated using an aromatic model compound, phenanthrene, and solid-state (13)C NMR analysis indicated more condensed aromatic structures when pyrolysis temperature increased or after activation process induced.
