摘要

Abstract

Ultrasonic-assisted extraction (UAE) combined with medium pressure liquid chromatography (MPLC) was designed for carbazole separation from anthracene slag (AS). The effects of liquid/solid ratio

temperature

and extraction times on carbazole separation were investigated. When using CCl

and ethyl acetate as extraction solvents and combining with MPLC

carbazole recovery and purity are 75.1% and 95.4%

respectively. The mechanism for carbazole separation were presumed by examining intermolecular interactions such as N-H…π

π-π

and C-Cl…π interactions. These results demonstrate that UAE/MPLC has a considerable potential as a green and promising strategy for separating and purifying carbazole and other chemicals from AS.
