Abstract

Adsorptive water purification methods were studied for the removal of phenol-type compounds (such as phenol/thymol) and humic acid applying sodium bentonite modified by cationic surfactant hexadecyltrimethylammonium bromide (HTAB). The effect of humic acid on adsorption of phenols was examined in pure and model thermal water. It was found that the efficiency of the removal of individual pollutants can be highly influenced if another pollutant is present. The main reason for the increased efficiency was identified by the means of infrared spectroscopy which proved that each pollutant modifies decisively the organophilicity of the clay surface. Furthermore, the studies performed in model thermal waters revealed that the presence of specific cations could further increase the removability of these pollutants.
