Coal fly ash zeolites as adsorbents for effective removal of heavy metals and dyes from contaminated waters
Zgureva D., (Corresponding) Boycheva S., Behunová D., Václavíková M.
Topic:
Wastewater treatment
Recently, the purification of enormous amounts contaminated industrial, agricultural and municipal waters increases the demands of low-cost and technologically feasible techniques. The application of natural zeolites in wastewater treatment is known from many years. A feasible approach for...Read more

Cobalt- and copper-modified coal fly ash nanozeolites for environmental protection applications
(Corresponding) Boycheva S., Marinov I., Lazarova H., Zgureva D., Václavíková M., Popova M.
Topic:
Nanomaterials in the environmnents applications and effects
Fly ash zeolites (FAZ) are promising materials for adsorbents, ion-exchangers and catalysts. FAZ usually possess a mixed micro-mesoporous structure that facilitates mass transport phenomena through their framework. Due to the transfer of iron spinel oxides and many metal species from the raw...Read more
Heat of adsorption in the fly ash zeolite – CO2 system at dynamic conditions
Zgureva D., (Corresponding) Boycheva S., Marinov I., Miteva S., Asenov A.
Topic:
Climate change mitigation and adaptation
The global warming represents one of the main world problems in the recent decades as it is considered that electricity production by coal burning is responsible for 40 % of the total CO2 emissions. The post-combustion capture of CO2 based on physical adsorption has the highest potential for...Read more
