Zeolite – phillipsite was modified with long chain organic surfactant – hexadecyltrimethyl-ammonium bromide (HB). Two different amounts of HB were used to modify the zeolitic surface (150 % and 200% of phillisite external exchange capacity - ECEC). Adsorption of non-steroidal antiinflam matory drug – ibuprofen (IBU) was studied at pH 7, at different initial drug concentrations. Adsorption increased with increasing the initial drug concentrations as well as with increasing amounts of organic phase at the phillipsite surface. From the Langmuir model, the maximum IBU adsorption capacity for phillipsite modified with surfactant at 150 % of ECEC was 12.72 mg/g, while for organophillipsite containing surfactant in amount of 200 % of ECEC, the maximum adsorption capacity was 18.25 mg/g.
