Two different surfactants, cetylpyridinum chloride (CP) and
hexadecyltrimethylammonium bromide (HDTMA) were used to modify the surface of a natural
zeolite - phillipsite (PHI) and adsorption of ochratoxin A (OCHRA) was investigated.
Adsorption experiments were done with different amounts of adsorbents and with different
initial OCHRA concentrations at pH 3 and pH 7. Results showed that modification of phillipsite
surface with CP and HDTMA significantly improved adsorption of OCHRA in comparison to
unmodified phillipsite. CP modified phillipsite showed similar adsorption behavior as HDTMA
modified phillipsite. The highest adsorption capacity for OCHRA was obtained with CP
modified phillipsite at pH 3.
