Využití uhlíkatých nanotrubiček pro odstranění ibuprofenu a diclofenaku z vod

Abstract

The aim of this work is to verify the possibility of using sorbents based on nanocarbon to remove drug residues from wastewater, specifically sorbents based on multiwalled carbon nanotubes. In this work have been used commercially available carbon nanotubes Nanocyl 7000 (NC7000) in its original raw from and also its modifications by oxidation with sodium hypochlorite (NC7000p). An interaction of both materials with ibuprofen and diclofenac was observed in model aqueous solutions. The results obtained showed that carbon nanotubes NC7000 and NC7000p are suitable adsorption materials for cleaning water and removal of ibuprofen, where sorption efficiency reached 80%. In the case of diclofenac was sorption efficiency of both types of nanotubes much lower, especially in the case of raw nanotubes (ca. 50%). Modification of the surface of the nanotubes with oxidation increased sorption efficiency of diclofenac to 66%. Different efficiencies are given by different properties and structure of both drugs.
