Department: Department of Analytical Chemistry Candidate: Adam Valachovič Supervisor: doc. RNDr. Dalibor Šatínský, Ph.D. Title of the diploma thesis: Modification of nanofibers for extraction in liquid chromatography The diploma thesis demonstrates the influence of modifications of polymer nanofibers on their extraction properties for extraction in liquid chromatography. Nanofibers represent a potential sorbent for extraction methods due to their large surface area, which leads to increased capacity of extraction. Another advantage of nanofibers is the possibility to modify their surface resulting in various nanofibers with different extraction properties. In this thesis, the modifications were performed by coating polypropylene nanofibers ...
