Abstrakt
Pollution caused by pharmaceuticals has become an increasingly serious issue,
therefore innovative and cost – effective methods of pharmaceutical’s removal must be studied.
Clay – humic acid composite materials can be considered as prospective and low cost sorbents
for contaminants. The aim of this study is to develop clay mineral and humic acid composite
materials and to characterise their possible applications. For this research, three types of clay
minerals (montmorillonite, kaolinite and bentonite) were modified with three types of humic
substances: technical humic acid from lignite, humic substances extracted from raised bog peat
and technical K humate from lignite. The sorption was characterised according to the chosen clay
mineral and humic acid type and concentration. The obtained material was characterised by
Fourier Transform Infrared spectroscopy and Scanning Electron microscopy. The composite
materials were tested for sorption of pharmaceuticals (chloropromazine hydrochloride). The
obtained results characterise clay mineral and humic acid composite materials’ possible
applications as sorbents for removal of pharmacologically active substances.
