Spectroscopic Characteristics of Humic Acids Originated in Soils and Lignite
humic acids UV-VIS FTIR and SFS spectroscopy
2015/3/1
The aim of our work was to characterise the stability, humification degree, and principal classes of fluorophores in humic acids isolated from different matrices. Soil humic acids were isolated from a...
OPTICAL PROPERTIES OF OPEN CAST LIGNITE MINING LAKES IN CENTRAL GERMANY
Dynamic processes Ecosystems Hyperspectral Monitoring
2015/2/3
The aim of the study is the characterisation of the optical properties of mining lakes. These optical properties will be used to the classification of remote sensing data and the spatial and temporal ...

Evaluation Impact Texas Lignite Development Texas Water Resources
2013/9/11
Fuel shortages and resultant rising fuel costs as well as federal policies prompting energy independence have served to encourage power companies to exploit available lignite deposits of the western s...
Demineralised Lignite Fly Ash for the Removal of Zn(II) Ions from Aqueous Solution
Fly Ash Zn(II) Ion Adsorption Kinetics Isotherm
2013/3/18
Among the various possibilities of limiting the disposal of fly ashes (lignite), their reutilization as adsorbent materials is worthy of consideration. To this end, proper ashes beneficiation techniqu...
