Large amounts of coal combustion products (as solid thermal power plants) with different chemical and physical properties cause serious environmental problems. Even though fly ash is a product, it has wide range applications (e.g., in construction, metallurgy, production, reclamation etc.). One its potential uses zeolitization to obtain higher added value the product. The aim this paper produce material sufficient textural used, for example, purposes (an adsorbent) and/or storage material....
In Slovakia, there are a number of contaminated sites that have occurred due to intensive mining, mineral processing, metallurgical activities, chemical industry, fossil fuel combustion, and industrial agriculture in the past. This paper summarizes occurrence, chemistry, toxicity, mineralogy arsenic species related soil water contamination Slovakia. Four main localities with exposure were identified. Additionally, magnetically modified carbon biochar (MWchar-Mag) was tested for removal from...
Methylene blue (MB) is one of the most widely studied organic molecules in treatment wastewater. Sorption, biodegradation, photodegradation, electrochemical oxidation, ozonation, and other advanced oxidative processes are frequently used to remove this dye from water solutions. The unexpected degradation MB adsorbed on magnetic biochar aqueous solution was observed. We found that conditions handling, such as drying temperature storage period, substantially influenced stability fixed...
The continued decrease in water quality requires new advances the treatment of wastewater, including preparation novel, effective, environmentally friendly, and affordable sorbents toxic pollutants. We introduce a simple non-conventional mechanochemical synthesis magnetically responsive materials. Magnetic lignite magnetic char were prepared by high-energy ball co-milling from either raw Slovak or coal-based together with ferrofluid. products characterised X-ray diffraction, electron...
Abstract In this paper, wheat straw and rapeseed residues before after microwave pyrolysis during biooil production were studied as potential sorbents of heavy metals. The characterized by elemental analysis FTIR spectroscopy. Sorption properties the materials investigated using batch adsorption-equilibrium experiments effect initial Cd Pb concentration was studied. experimental data fit Langmuir adsorption isotherm. maximum sorption affinity observed in case its capacity 31.6 83.5 mg/g for...
Asbestos is the common name applied to a group of natural, fibrous silicate minerals, which were once one most popular raw materials be used in building materials. was mainly for production assortment asbestos cement products. Today it generally known that belongs hazardous and shows carcinogenic activity. It therefore advisable attempt dispose minerals asbestos-containing convert them into harmless material. One methods may microwave thermal decomposition minerals. The research old etemit...
Availability of water may influence activities all living organisms, including cyanobacterial communities. Filamentous cyanobacterium Nostoc commune is well adapted to wide spectrum ecosystems. For this reason, N. had develop diverse protection strategies due exposition regular rewetting and drying processes. Few studies have been conducted on activities, by which cyanobacteria are trying avoid deficit. Therefore, the present study using physiological morphological parameters focused...
The contribution deals with the study on composition of ochre sample from Marta adit at Nižná Slaná. Three samples were prepared by hand picking and screening, which subjected to GA, AAS, XRF XRD. Salts precipitated surface drying contain 17.7 % S (53 as SO4), 16.5 MgO, 13.6 Fe2O3, 3.54 CaO 1 MnO. As mineral composition, sulphates such gypsum, starkeyite rozenite are dominant. fraction grain size under 250 micron contains 30 28.6 SiO2, 8 Al2O3, 6.6 CaO, 2.9 MgO 1.95 S. Notable is content...
