Interaction of drugs with soil organic matter - calorimetric study
Papko, Nadezhda ; Sedláček, Petr (referee) ; Klučáková, Martina (advisor)
This bachelor thesis is focused on the study of the interaction of soil organic matter with selected drugs using isothermal titration calorimetry. Two fulvic acids and drugs were used in the experiment: ibuprofen, pyridine sulfate and diclofenac. The scope of the work was to test the method for studying the interactions between fulvic acids and drugs and to optimize it for specific humic substances and drugs. Isothermal titration calorimetry includes the possibility to determine very important thermodynamic parameters, which were determined during the measurement of the bachelor's thesis. The main goal was to measure and assess whether the interactions take place and what the thermal effects are.

Interactions of pharmaceuticals with fulvic acids – calorimetric study
Papko, Nadezhda ; Sedláček, Petr (referee) ; Klučáková, Martina (advisor)
Tato diplomová práce se zaměřuje na studium interakcí mezi půdní organickou hmotou a vybranými léky pomocí izotermické titrační kalorimetrie. V rámci experimentu byly použity tři fulvinové kyseliny a léky: ibuprofen, diclofenac a sulfapyridine. Vybrané léky a fulvinové kyseliny byly rozpouštěné v roztocích NaCl a MgCl2, jelikož kovové ionty jsou přítomny v organickém materiálu půdy. Mobilita léčiv závisí na sorpci, což je interakce mezi léčivy a půdními částicemi. Faktory ovlivňující sorpční chování zahrnují vlastnosti léčiv, půdy a enviromentální podmínky. Během bakalářské práce podražilo optimalizovat metodu ITC pro daný studiu, což usnadnilo experimentální práce a zlepšilo vyhodnocení dat. Pomocí metody byli stanovené tepelné efekty (naměřené a porovnané) interakcí mezi fulvinovými kyselinami a léky.
