Abstract:
The contamination of phenols in the environment is a serious concern. Because of their toxicity and
carcinogenic properties, several phenols have been classified as priority pollutants. Gas chromatography (GC)
with polysiloxane stationary phases were generally used to analyze phenols in a mixture. Nevertheless,
incomplete separation and/or coelution were observed for several pairs of phenols. In this work, the separation
of 18 underivatized phenols mixture (phenol, chlorophenols, methylphenols, and nitrophenols) was studied
by GC with split injector (250 *C) and flame ionization detector (250 *C). The carrier gas was hydrogen.
Three types of stationary phases were alpha-, beta-, and gamma-methylated cyclodextrins of different ring
size. Results showed that all three derivatized cyclodextrin stationary phases could improve the separation of
phenols mixture compared to polysiloxane stationary phase. Some incomplete separations were still observed
for a few peaks with beta- and gamma-methylated cyclodextrin stationary phases. Interestingly, small-size
alpha-cyclodextrin stationary phase provided complete separation for all 18 phenols mixture. Using a capillary
column of 15-meter long and a temperature program from 130 to 220 'C, the separation was accomplished in
less than 10 minutes
