The study of the interactions between nanoparticles (NPs) and proteins has had a pivotal role in facilitating the understanding of biological effects and safe application of NPs after exposure to the physiological environment. ...
Removal of copper, cadmium, and zinc from the mine wastewater in RTB Bor by low cost adsorbent fly ash
(Bor : University of Belgrade - Technical Faculty in Bor, 2013)
Using fly ash, lignite and mixture of lignite and fly ash for the removal of Cu, Cd and Zn from the acid mine wastewater was studied. The batch and dynamic experiments were conducted. Analysis of mine wastewater proved ...
Copper removal by pelletized fly ash
(Belgrade, Serbia : University of Belgrade - Faculty of Mining and Geology, 2021)
The increasing levels of industrial wastewater that are released to the environment present a serious threat to human health, living resources, and ecological systems. Fly ash was tested for the removal of Cu2+ from ...
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 ...
Adsorption properties of TENT fly ash in removal of copper from wastewater
(Bor : University of Belgrade - Technical Faculty in Bor, 2013)
