The removal of mercury from water by open chain ligands containing multiple sulfurs

Water assisted synthesis of MWCNTs over natural magnetic rock: An effective magnetic adsorbent with enhanced mercury(II) adsorption property

“…The thermodynamic parameters for the adsorption process, DH (kJ mol À1 ), DS (J K À1 mol À1 ) and DG (kJ mol À1 ) could be evaluated using the Eqs. (6)(7)(8) [48], where R and T are the gas constant (8.314 Â 10 À3 kJ K À1 mol À1 ) and absolute temperature (K), respectively.…”

“…The maximum allowable level for mercury(II) in surface waters is 0.07 lg L À1 [4]. Mercury(II) is released into the environment via textile factories, ores mining and smelting, burning of fossil fuels and chlor-alkali plants [5][6][7]. Accordingly, extensive studies have been performed to develop mercury(II) removal techniques which include precipitation, membrane filtration, ion exchange, adsorption and bioremediation [8][9][10][11].…”

Mercury Removal in Simulated Flue Gas by Oil Palm EFB Activated Carbon

“…Flue gas consists of three forms which are oxidized form (Hg 2+ ), particulate form (Hg p ) and elemental form (Hg 0 ). The elemental mercury (Hg 0 ) is the predominant form of atmospheric Hg, which has a long residence time in the atmosphere from 0.5 to 2 years and can be dispersed and deposited in remote places even 1000 km away from the sources [1,2].…”

Dowex anion exchanger-loaded-baker’s yeast as bi-functionalized biosorbents for selective extraction of anionic and cationic mercury(II) species

“…Preparation of xylenol orange functionalized silica gel as a selective solid phase extractor and its application for preconcentration and separation of mercury from water was also reported [15]. The extraction behavior of 1,3-dipropyn-2-yl-oxycalix [4]arene towards mercury(II) ion was examined and reported [16]. A method employing dual competitive ligand exchange by application of two competing ligands, diethyldithiolcarbamate (DEDC) and thiosalicylic acid (TSA), followed by solid phase extraction (CLE-SPE) for complex characterization of inorganic Hg(II) in natural waters was described [17].…”

“…In addition, recovery of mercury is also important from the economical point of view due to a wide range of medical, chemical and industrial mercury applications including dental amalgams, anti-fouling paints, electrolysis and electrochemistry, batteries, fluorescent lamps, catalysts as well as many consumer products such as mercury lamps [4][5][6][7].…”
