Sorption study on diclofenac removal using organo-beidellite

Popis výsledku v původním jazyce

The aim of this study is the assessment of ability of organo-beidellite for the removal of drugs from aqueous solutions due to increasing wastewater pollution related to high consumption of pharmaceuticals. The beidellite was modified with cetylpyridinium chloride and tested as potential sorbent for analgesic drug diclofenac from aqueous solutions. The samples were characterized by X-ray powder diffraction, simultaneous thermogravimetry and differential thermal analysis and infrared spectroscopy along with UV-VIS spectroscopy. The enhancement of the basal spacing obtained by X-ray diffraction confirmed the intercalation process of organic substance into beidellite. The results obtained by TG/DTA showed that intercalation caused decrease in dehydration and increase in dehydroxylation temperatures due to an increase of the hydrophobicity of modified beidellite. The sorption experiments exhibited the increasing of sorption capacity related to the increasing of initial concentration of diclofenac in solution. The removal of diclofenac from aqueous solution reached up to 96%.
