The ability of natural clinoptilolite and its modifiedforms were studied for removal
ofPAHs from n-paraffin. Surfactant modified zeolite (SMZ) was obtained by modifYing clinoptilolite
with hexadecyltrimethylammonium ion. Homoionic forms ofzeolite were obtained by ion exchange
process using inorganic salts ofdesirable cations (e.g. Ag+, Fe3
+ .• .). Natural clinoptilolite and its
cation exchanged forms show small affinity toward PAHs, due to their hydrophil nature, whereas
SA4Z removed more than 50 percent of the initial PAHs contents of n-parafJin. The structure of
zeolite did not change upon modification. Regeneration of zeolite was performed efficiently with
chloroform.
