Kinetics of copper adsorption from wastewater by lignite
(Sofia, Bulgaria : Publishing House “St. Ivan Rilski”, 2013)
Kolubara lignite was used as a natural and low cost adsorption material for removal of copper (Cu2+) from the aqueous solutions. As a method, batch adsorption procedure was applied. Results show that domestic lignite is ...
Adsorption isotherms of removing copper from aqueous solutions by low cost adsorbent-lignite
(Sofia, Bulgaria : Publishing House “St. Ivan Rilski”, 2013)
Serbian lignite from ’’Kolubara’’ deposit was used as a low cost adsorbent for removal of copper ions (Cu2+) from aqueous solutions. Lignite was subjected to the elementary and technical analysis as well as BET and FTIR ...
Concentration method for the mining wastewater-valorization of the copper
(The Regional Environmental Center for Central and Eastern Europe, 2013)
During the mining process of copper exploitation, a large amount of wastewater is generated. Not only do the copper ions contaminate the water but also represent a great loss for the copper production industry. Negative ...
