Coal is the most important and widespread fuel sedimentary rock of organic origin. It is one ofthe main energy sources today and an industrial raw material for various products. Together withthe oil and other natural bitumens, it belongs to the group of fossil fuels or caustobiolite.Combustion represents one of the fundamental energy transformation...

Particulate matter enters the atmosphere as a result of human activity, as well as natural processes.Since we still cannot influence natural processes, reducing the concentration of floating particlesis possible only by adjusting human activity. The emission of solid particles occurs during a largenumber of everyday activities. Depending on the act...

Leachate water from sanitary landfills represents one of the most complex global environmentalproblems. This paper examines the possibility of using aluminosilicate material, pyrophyllite, fromthe Parsovići deposit, as an adsorbent. It was researched the influence of two granulations ofpyrophyllite (0-53 μm and 0-100 μm) on the degree of adso...

Three new neutral complexes of copper(II) containing chalcone ligands derived from 2'-hydoxyacetophenone and 4-substituted benzaldehydes were synthesized. Complexes were preparedby solution synthesis and characterized by spectroscopy. The catalytic activity of complexes wasexamined in the reaction of 3,5-di-test-butyl catechol (DTBC) oxidation. The...

Pyrophyllite (Al2Si4O10(OH)2) is a layered phyllosilicate mineral with a basic 2:1 crystal structure,consisting of an aluminum octahedral layer placed between two silicon tetrahedral layers (T-O-T),connected by weak Van der Waals forces, which results in easy structural disruption. Naturalpyrophyllite has an electroneutral surface, which causes a h...
