Changes in arsenic binding and arsenic migration during the oxidation of loellingite and arsenopyrite: Case study from anthropogenic arsenic deposit at the Přebuz locality, Krušné hory Mts
Filippi, Michal
Anthropogenic anomaly at the Přebuz deposit has been used studied as a mineralogical model and geochemical model for study of weathering of arsenopyrite-loellingite concentrate under climatic conditions. Presented contribution is aimed at newly growing secondary minerals identification, at mineral succession determination, and at preliminary evaluation of the arsenic contamination.
Selektivita mokré oxidace v periodicky řízeném zkrápěném reaktoru
Tukač, V. ; Chyba, V. ; Hanika, Jiří
The objective of this work was to investigate the impact of dynamically changing extent of wetted catalyst surface and mass-transfer of gaseous oxygen on oxidation of the aqueous phenol under periodic modulated liquid feed rate. Selectivity of oxidation and reactor productivity was also under consideration in this study.
