Modifications of black carbons and their influence on pyrene sorption
Wen Zhang,Lei Wang,Hongwen Sun +2 more
TL;DR: In most cases, the change in sorption capacity could be explained by the changes in C content and type, polarity, surface area, and micropore volume of the BCs; however, the role of conformation (the accessibility to sorption sites) could not be ignored.
