Carbon particles in mine-stone dumps after bituminous coals mining
Sýkorová, Ivana ; Havelcová, Martina ; Klika, Z. ; Trejtnarová, Hana ; Fojtíková, M. ; Šulc, Alexandr
The influence of heating on optical properties and morphology of organic matter was studied in mine-stone dumps in three districts in the Czech Republic.
Organic compounds in hardcoal waste piles studied by GC/MS and Py-GC/MS
Havelcová, Martina ; Sýkorová, Ivana ; Klika, Z. ; Trejtnarová, Hana ; Fojtíková, M.
GC/MS and Py-GC/MS techniques were used to provide information on set of samples from three waste piles localities in Czech Republic. Substituted and unsubstituted phenantrenes and other polycyclic aromatic hydrocarbons were comprised in sample extracts. The results were correlated with petrographic composition.
Determination of motor fuels composition by methods of 1H NMR spectroscopy
Trejtnarová, Hana
Content of polyaromatic hydrocarbons was determined in diesel fuels by 1H NMR, HPLC a LSC. Olephines and aromatics were determined in gasolines by 1H NMR a GC. Results of 1H NMR were compared with those of chromatograpic methods.
Lignite deposits between Moravská Třebová and Kunštát, by Uhelná, Dolní Životice by Opava and in neighbourhood Brno
Pešek, J. ; Sýkorová, Ivana
The petrographical and elemental composition and technological parameters of Cenomanian and Miocene lignite were discussed.
