Comparative uptake study of toxic elements from aqueous media by the different particle-size-fractions of fly ash

Heavy metal characterization of circulating fluidized bed derived biomass ash

“…CaO is much higher when the fuel is ligneous. CaO may be generated automatically by the decomposition of CaCO 3 soon after the fuel burns and then subsequently transforms into microcrystallic secondary calcite [22]. The high content of CaO resulted in alkaline ash, and self-desulfurization was achieved for CFB.…”

Post-combustion CO2 adsorption on activated carbons with different textural properties

“…Nonetheless, numerous research studies are devoted to the development of high-efficiency CO 2 capture processes which can overcome the techno-economic limits associated with MEA use (such as equipment corrosion, high energy consumption for the solvent regeneration, solvent cost and regeneration) [5,7]. In this context, adsorption onto porous solids is an effective and versatile technique for the removal of different classes of pollutants from gaseous or liquid streams, thanks to the potentially high selectivity toward the target contaminant and its general low maintenance costs [8][9][10][11][12][13][14][15][16][17]. For CCS application, different classes of adsorbents, such as carbonaceous materials, zeolites, mesoporous silicas, metal organic frameworks, molecularly imprinted sorbents etc., are currently being investigated [8,13,16,[18][19][20][21][22].…”

Reduction of Toxic Element Mobility in Mining Soil by Zeolitic Amendments

“…Srivastava et al, 2006;Pehlivan et al, 2006;Itskos et al, 2010 andAlexopoulos et al, 2013), radionuclides, and organic pollutants as well (e.g. Sun et al, 2010;Karagozoglu et al, 2007 andJanos et al, 2003), has been extensively discussed.…”
