Activation of biochar from wheat bran
Sauchanka, Katsiaryna ; Kalina, Michal (referee) ; Pořízka, Jaromír (advisor)
This graduation work is devoted to the issue of biochar production from wheat bran and ways of its surface activation. The theoretical part summarizes information about biochar, its physico-chemical properties, production methods and surface modification options. It also contains description of EBC certificate, that sets requirements for biochar which is placed on the market. The practical part of the work focuses on activating of the biochar surface and comparing the results with the available literature and European biochar certificate.

Zinc in food suplements
Sauchanka, Katsiaryna ; Suková, Petra (referee) ; Řezáčová, Veronika (advisor)
The aim of this bachelor thesis was to determine zinc in the dietary supplements by the voltammetric method. The general properties of zinc, its occurrence, toxicity and influence on human health are described in the first part. Next the methods, including a detailed description of the voltammetric analysis, are summarized. The experimental part is focused on the process of optimization of the conditions for zinc voltammetric analysis and the application of the optimised method on real samples.
