چکیده
Identifikácia organických látok v slovenskom hnedom uhlí Vzorky slovenského hnedého uhlia z lokality Cígeľ a Handlová boli podrobené nadkritickej fluidnej extrakcii (SFE) oxidom uhličitým, modifikovaným 5 % metanolom. Extrakty, získané metódou SFE, boli podrobené plynovej chromatografii s hmotnostno-spektrometrickou identifikáciou (GC MS). Porovnaním s literárnymi údajmi hmotnostnej spektroskopie, prístroja boli k jednotlivým pikom priradené najpravdepodobnejšie vzorce a zlúčeniny. Identifikácia potvrdila organické komponenty, ako kaurány a deriváty kyseliny kauránovej, s významnou biologickou aktivitou.

متن کاملChemical and physical characteristics of substrate material for plant growth on coal wastes in rangelands of Kiasar, Sari, Mazandaran province
Background and objectives Mining results in degradation of rangelands ecosystem structure and function. Coal mining in rangelands produces significant quantities of waste dumps in mining area which are considered as the main environmental pollutants in the site and surrounding ecosystems. Vegetation restoration in mining area could reduce soil pollution and could be of great help in restoring ...
متن کاملImportant fossil source contribution to brown carbon in Beijing during winter
Organic aerosol (OA) constitutes a substantial fraction of fine particles and affects both human health and climate. It is becoming clear that OA absorbs light substantially (hence termed Brown Carbon, BrC), adding uncertainties to global aerosol radiative forcing estimations. The few current radiative-transfer and chemical-transport models that include BrC primarily consider sources from bioge...

The Ghoznavi coal mine, as an active mine in Golestan Provice, is located about 45km south of Azadshahr. Coal extracted from first (I) and third (Ш) coal layers. XRD and SEM/EDS studies indicate the presence of quartz and clay minerals as major and pyrite (arsenopyrite), gypsum, jarosite (natrojarosite), goethite, hematite, plagioclase, K-feldspar, rutile and corundum as minor minerals. After c...
متن کاملIsolation and identification of aquatic saprolegnious stramenopiles in Fars and Kermanshah provinces (west of Iran)
The order Saprolegniales includes pathogenic species of aquatic and terrestrial plants and aquatic animals including fish. These straminipilous fungi play an important role as a decomposing component which participates in the destruction processes of organic substrates and self-cleaning biological processes in freshwater ecosystems. In this study, samples of brown decayed twigs, leaves, woods a...
