Removal of mercury in aqueous solution by fluidized bed plant fly ash

Treatment Tank Corrosion Studies for the Enhanced Chemical Cleaning Process

“…Iron and aluminum oxides are initially entrapped on the surface of the coupon with the iron oxalate. The mercuric species is adsorbed from the solution by the aluminum oxides [36]. If the temperature is high enough, the aluminum oxide begins to dissolve leaving either a mercuric or mercurous species present on the surface.…”

Synthesis and characterization of a crosslinked chitosan derivative with a complexing agent and its adsorption studies toward metal(II) ions

“…[3][4][5] Metals can be distinguished from other toxic pollutants, since they undergo chemical transformations, are non-biodegradable, and have great environmental, economic, and public health impacts. 6,7 The chitosan (CTS) biopolymer has proved to be an effective transition metal ion adsorber. Chitin/chitosans, which are unique even among polysaccharides, contain amino groups as constituent carbohydrate units, so that their use in conjunction with chemical crosslinking agents such as isocyanates, aldehydes, and carbodiimides in wound dressings, anti-adhesion materials, and metal ion absorbents has been studied.…”

Comparison of fly ash properties from Afsin?Elbistan coal basin, Turkey

“…Potential applications for fly ash are grouped into following main categories: construction materials (cement production, concrete, ceramics, glass and glass-ceramics), geotechnical applications (road pavement and embankments), agriculture and miscellaneous (sorbent and sludge conditioning) [3]. A large amount of information is available on the application of coal fly ash [4][5][6][7][8][9][10]. Bayat [11,12] studied the AE fly ashes, for their ability to remove nickel [Ni(II)], copper [Cu(II)], zinc [Zn(II)], Cr(VI) and Cd(II) from an aqueous solution.…”
