Multi-walled carbon nanotubes (MWCNTs) can selectively

adsorb structurally-similar liquiritin and isoliquiritin, both of

which are flavonoid compounds. The adsorption thermodynam-

ics of isoliquiritin on MWCNTs was investigated. Results indicate

that the quantity of isoliquiritin adsorbed increases with isoli-

quiritin concentration and decreases with temperature. Adsorp-

tion data can be well described by the Freundlich equation. The

values of DH0 and DG0 indicate that the adsorption is a spontane-

ous exothermic process.

Professor Fu He was born in Jiaocheng County, Shanxi Prov-

ince, China. He has been working in the Institute of Coal Chemis-

try, Chinese Academy of Sciences since graduation from Shanxi

University in 1964. He had undertaken and completed many

research projects as a principal or main investigator during R&D

and industrialization studies in the field of carbon fibers for over

forty years. He has authored four books, held twelve patents,

and published 120 research papers. Two of his books, “The prepa-

ration, properties and applications of carbon fibers” and “Carbon

fibers and the techniques for application” have been recognized

as classic textbooks by many researchers in the field of carbon

fibers in China. A total of fifteen scientific achievements have been

developed by him, five of which have been applied in the industri-

alization of carbon fibers. He received the State Council Special

Allowance in 1992, and was awarded the National Young and Mid-

dle-aged Experts with Outstanding Contribution Award in 1988,

the Excellent Graduate Supervisor of Chinese Academy of Sci-

ences in 1998, the Second-Class Merit by the Labor Emulation

Committee of Shanxi Province in 1999, and the Distinguished

Achievement Award on Carbon Materials in 2009.
