“…Examinations of a number of particles with sizes from 10 to 200 nm showed that all particles had similar surface layers, which resulted from the oxidation and reaction with oxygen and water. It verifies that nZVI has specific core-shell structure, a core of zero-valent iron and a thin shell of iron oxides [21,22]. The XRD pattern ( Fig.…”

“…Basically, no compelling evidence of any form of iron oxyhydroxide was found in our samples; this can be rationalised by recognising that under alkaline conditions; Fe(III) could transform into from b-FeOOH and then to a-Fe 2 O 3 , and moreover, either goethite (a-FeOOH) or akaganeite (b-FeOOH) can transform into a-Fe 2 O 3 [43], which means that the signal appearing at 2q ¼ 24 could very well be due to either of those species after transforming into aFe 2 O 3 . However, this very same signal could be related with Fe(OH) 2 , which can be further oxidised into either magnetite (cubic spinel Fe 3 O 4 ) [44], goethite, akaganeite or lepidocrocite (g-FeOOH) [45], to finally transform into a-Fe 2 O 3 . Magnetite can also undergo transformation into g-Fe 2 O 3 and then into aFe 2 O 3 [46].…”

Available online xxx Keywords:Iron electrode NiFe Electrolyte decompositionCell performance Hydrogen evolution a b s t r a c t Aiming to develop a cost effective means to store large amounts of electric energy, NiFe batteries were produced and tested under galvanostatic conditions at room temperature.Multiple regression analysis was conducted to develop predictive equations that establish a link between hydrogen evolution and electrode manufacturing conditions, over a wide range of electrode/electrolyte systems. Basically, the intent was to investigate the incidence of lithium hydroxide and potassium sulphide as electrolyte additives on cell performance. With this in mind, in-house built Fe/FeS based electrodes were cycled against commercially available nickel electrodes on a three electrode cell configuration. A 3 Â 4 full factorial experimental design was proposed to investigate the combined effect of the aforementioned electrolyte additives on cell performance. As a consequence, data from 144 cells were finally used in conducting the analysis and finding the form of the predictive equations. Our findings suggest that at the level of confidence alpha ¼ 0.05, the presence of relatively large amounts of the soluble bisulphide would enhance the performance of the battery by reducing electrolyte decomposition.

“…Daphnia magna survival exposed to nZVI (Fe 5mg/L) drops within 96 h (Keller et al, 2012). In addition, nZVI is also potentially toxic to nerve cells, animal cells, and human cells (Phenrat et al, 2009;Crane and Scott, 2012;Kharisov et al, 2012). One possible explanation is the physical disruption of cell membranes by nZVI.…”

Pharmaceuticals are detected at trace levels in waters. Their adverse effects on aquatic ecosystems and human health demand novel pharmaceutical removal technologies for treating wastewater effluents. Iron (Fe) or manganese (Mn) may play important roles in these new technologies since these metals are abundantly available at low costs and are known to contribute to organic conversions via physico-chemical, chemical, and biologically related processes. Few reviews describe and discuss Fe-or Mn-based technologies for the purpose to remove pharmaceuticals from water. Therefore, we review the current literature sorted into the three removal mechanisms, that is., through physico-chemical, chemical, and biological processes. The principals, performance, and influential parameters of these three types of technologies are described. Current and potential applications of these technologies are critically evaluated in order to identify advantages and challenges. In addition, the Fe-or Mn-based technologies which are currently not used but promising to further develop to remove pharmaceuticals cost efficiently are proposed.
