Utilization of flow-through coulometry for study of reactivity of humic acids
Pavlíková, Marcela ; Sýkorová,, Ivana (referee) ; Klučáková, Martina (advisor)
Humic acids are part of humus material abounded in nature. Humic acids are generally aromatic stuffs with sidechains and there can be linked various functional groups as carboxylic and fenolic mainly. This functional groups are able to form transitions elements ions and complexes of different stability. This property can be used in the environment, because certain polutants should be imobilized in nature. Diploma thesis studies adsorption of metal ions Cu2+, Cd2+, Zn2+ and Pb2+ on humic acids by electroanalytical method called flow – through coulometry.

Study on sorption of inorganic nutrients on lignite
Vahala, Jan ; Klučáková, Martina (referee) ; Sedláček, Petr (advisor)
Although lignit represents a valuable chemical substrate, it has been utilized mostly as a fuel in energetic industry. This application is not cost-effective at all and provides a negative ecological impact. Therefore, this bachelor thesis focuses on sorption properties of lignite utilizable in its alternative, mostly agricultural applications. Experimental part of the work deals with sorption and desorption of model inorganic nutrients (nitrates and phosphates as main components of standard inorganic fertilizers). Results of the experiments provides closer view on an application potential of lignite as a carrier of these nutrients or as an organic supplement to traditional NPK agricultural fertilizers.
