http://dx.doi.org/10.1016/j.jes.2015 1001-0742/© 2015 The Research C Arsenic is one of the most common inorganic contaminants in groundwater worldwide, mainly due to the release of naturally occurring arsenic from aquifer sediments (Amini et al., 2008; Li and Cai, 2015; Rahman et al., 2015). Naturally occurring arsenic exists predominantly in arsenate and arsenite species in groundwater. Arseni...

Reaction of the nitrosylated-iron metallodithiolate ligand, paramagnetic (NO)Fe(N 2 S ), with [M(CH 3 CN) n ][BF 4 ] salts (M = Ni II , Pd and Pt ; or 6) affords di-radical tri-metallic complexes in a stairstep type arrangement ( [FeMFe] 2+ M...

The potential for reuse of iron-rich sludge from waterworks as a replacement for commercial iron salts in wastewater treatment was investigated using acidic and anaerobic dissolution. The acidic dissolution of waterworks sludge both in sulphuric acid and acidic products such as flue gas washing water and commercial iron solution was successful in dissolving the iron from waterworks sludge. The ...

Major uncertainties exist with respect to the aqueous geochemical evolution of the Martian surface. Considering the prevailing cryogenic climates and the abundance of salts and iron minerals on Mars, any attempt at comprehensive modeling of Martian aqueous chemistry should include iron chemistry and be valid at low temperatures and high solution concentrations. The objectives of this paper were...

Thousands of medium and low steam boilers hot water operate in the country's industry, municipal energy agriculture. Their reliable operation is largely determined by maintenance a rational water-chemical regime. The main problems source are presence dissolved oxygen, iron ions, salts calcium, magnesium.
 aim work to analyze existing technologies equipment for treatment different types boi...

Raji, a malignant B-lymphocyte cell line containing Epstein-Barr virus genomic elements, has been conditioned to proliferate optimally in transferrin (Tf)-free medium containing a very low concentration of an iron salt. We provide evidence that an Tf-independent iron uptake system is physiologically important for maintaining the growth of these cells. The data show that Raji cells take up iron ...

The significant progress made in the context of iron-catalyzed cross-coupling reactions past several years has boosted competition with well-known nickel and palladium catalyst systems. Iron-catalyzed protocols not only benefit from economic toxicology standpoints, but also exhibit a range reactivities tolerate many functional groups. To date iron systems have been developed, ranging use simple...

The supply of iron to plant roots was one of the main problems in water culture until about 1950. The main source of iron was originally ferrous sulfate, already used by Sachs (9). It had to be supplied almost daily to the nutrient solution as it precipitates gradually. Some improvement was obtained with organic compounds, mainly ferric citrate, introduced by Gile and Carrero (4). The favorable...
