Monitoring the effectiveness of selected adsorbents in removing AOX from water
Rutarová, Natálie ; Kotzurová, Iveta (referee) ; Repková, Martina (advisor)
The diploma thesis was created in cooperation with the company Art Carbon and is focused on monitoring the effectiveness of ART SAND adsorbents in removing AOX from water. The theoretical part provides an overview and basic characteristics of AOX, their impact on the environment and the possibility of their removal. The experimental part is focused on the study of the effectiveness of selected adsorbents with the subsequent use of high performance liquid chromatography (HPLC) with UV detection. Two ART SAND, ASSP50 and ASPP50-X adsorbents, supplied by ArtCarbon, were selected 2,4-dichlorophenol and 2,6-dichlorophenol to monitor adsorption.

Ecotoxicological assessment of biochar from sewage sludge
Kotzurová, Iveta ; Vávrová, Milada (referee) ; Zlámalová Gargošová, Helena (advisor)
The aim of this diploma thesis is to assess the ecotoxicological effect of biochar produced from sewage sludge. In case of application of biochar to agricultural land, both the soil and aquatic ecosystem may be affected therefore contact and aquatic tests were chosen to assess the ecotoxicological effects. Representatives of soil invertebrates were earthworms Eisenia fetida; Daphnia magna and Artemia salina were chosen from aquatic animals and terrestrial plants were represented by Lactuca sativa, Sinapis alba and Allium cepa. The results of contact tests point out how ecosystem could be negatively affected by biochar dose. Through aqueous extract were shown differences in sensitivity of individual organisms in aquatic tests. Dried sewage sludge was found to be the biggest burden for all tested organisms. The pelletized biochar with the addition of an additive showed the lowest negative effect on tested organisms.
