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

Comparative studies of the equilibrium adsorption of CO2 onto coal ash zeolites Na-X and Na-Ca-X

(Corresponding) Boycheva S., Marinov I., Miteva S., Zgureva D.
Topic: 
Climate change mitigation and adaptation
Coal-fired Thermal Power Plants (TPPs) are the main source of greenhouse gas emissions in the atmosphere, but they also generate huge amounts of solid by-products, including fly ash (FA). A modern strategy for sustainable energy production is to improve the ecology of the TPPs by developing...Read more

Adsorption of Gatifloxacin from Aqueous Solution with Highly Stable Zr(IV)-Based Porphyrinic Metal-Organic Frameworks

Chen J., Wang L., Xu G., (Corresponding) Wang X., Zhao R.
Topic: 
Nanomaterials in the environmnents applications and effects
Water stable Zr-metal–organic framework nanoparticles (PCN-224 NPs) have been solvothermally synthesized. PCN-224 NPs show spherical shape with smooth surface and particle size of approximately 200 nm. PCN-224 NPs can be stable in acid and aqueous solutions, as confirmed by powder X-ray diffraction...Read more

Adsorptive Removal of Marbofloxacin from Milk using Activated Carbons.

GE X., WU Z., KUNZ W., Barge A., (Corresponding) Giancarlo C.
Topic: 
Water and wastewater treatment and reuse
The present study aims to remove the residual marbofloxacin (MBX) from milk with activated carbons (ACs) in batch and flow systems to meet the maximum residue limits (MRLs, 0.075 µg mL-1). Different types (granular and powder) and amounts of ACs were studied. In batch mode, 50 mg of commercial...Read more
