A study of weathered coal spectroscopic properties

摘要: Abstract Current coal industry causes significant environmental pollution and the most air deaths in world, making development of new eco-friendly applications one top priorities. Coal contains up to 50 % humic substances (HS), majority which is acid (HA). HA well known for its beneficial properties thus compounds extracted from can be used develop applications. To address this issue, we assessed structural composition HS by measuring their spectroscopic properties. As result, obtained spectra identify information about molecules allowing describing HS. The purpose study was weathered regards finding uses otherwise neglected natural resource. results show that relatively high oxygen content indicate transformations O-containing functional groups. Weathered has amount bioactive as condensed aromatics. major forming are acridine, anthracene, perylene, tetracene naphthalene it does not depend upon where site located.
