摘要

The paper deals with fabrication of carbonized and hydrophobized clinoptilolite-rich tuff using organic carbon rich substances, which were pyrolytic combusted and covered the external zeolite surface. Hydrophobization of the zeolite external surface was accomplished by octadecylammonium surfactant. Both surface modified clinoptilolite-rich tuffs were tested and compared to each other in regard to organic (phenol) and inorganic (chromate, arsenate) pollutants removal from aqueous solutions and so far elaborated composites with surface adsorbed pollutant species were analyzed by X-ray photoelectron spectroscopy (XPS).
