Soil salination and natural lignite as a potential remediating agent
Kořínková, Alena ; Sýkorová, Ivana (referee) ; Pekař, Miloslav (advisor)
This bachelor thesis deals with sorption ability of raw and water washed lignite for salt NaCl from water solution. Measurement was carried out in accordance with norm ČSN 11265 Quality of soil – Determination of electric conductivity with some modification (time period, extraction agent). Behaviour of lignite-water-NaCl, soil-water-NaCl and soil-lignite-water-NaCl mixtures was studied by measuring pH and electric conductivity.

Development of non-energy use of lignite
Macháčková, Mirka ; Sedláček, Petr (referee) ; Pekař, Miloslav (advisor)
This bachelor thesis deals with the study of non-energetic use of lignite. The use as a sorbent is one of many possibilities. Sorption of chloride and sodium ions was carried out on natural lignite from the South Moravian, lignite washed with deionized water and lignite enriched with calcium ions. The experiments were realized monitoring pH, electrical conductivity, amounts of sodium and chloride ions in the prepared samples. Chemical oxygen demand was determined in the extract of lignite. This measurement was carried out in accordance with norm ČSN 83 0540-8 Chemical and physical analysis of waste water: Determination of dichromate oxidability. For use in agriculture were investigating the possibility of preparation of humic hydrocolloids by high speed dispergator and planetary mill. The ideal ratio of lignite and water was determined. The liquid and solid humic hydrocolloids were prepared by mechanochemical activation the lignite. These were characterized - particle size, UV-VIS spectroscopy of prepared extracts and sedimentation.
