In this research iron manganese oxide nanocomposites were prepared by co-precipitation, sol-gel and mechanochemical methods by using iron (III) nitrate, iron (II) sulfate and manganese (II) nitrate as starting materials. These nanocomposites were prepared in the presence of various catalyst beds. The polyvinyl pyrrolidon (PVP) was used as a capping agent to control the agglomeration of the nano...

Colorimetry of iron in serum with Ferrozine (as used in the Technicon SMAC) or with bathophenanthroline (as used in the Du Pont aca) is influenced by EDTA, in contrast to such measurements with atomic absorption spectroscopy. Therefore EDTA contamination should be avoided with these colorimetric methods. If, however, contamination with EDTA is suspected, addition of zinc sulfate to serum or to ...

Recent advances in alternative water desalination technologies have become increasingly common, due part to expanding scarcity and the ability deliver usable without high energy cost advanced infrastructure required of traditional such as reverse osmosis (RO). One emerging technology is iron-based or use nano- (or micron-sized) metals (principally iron) desalinate water. In this study, was coup...

An organically templated iron sulfate of the formula @HN(CH2)6NH#@Fe Fe2 F6(SO4)2#•@H3O# possessing the kagomé lattice has been prepared and characterized by single-crystal crystallography and other techniques. This mixed-valent iron compound shows complex magnetic properties including spin-glass behavior and magnetic hysteresis. The low-temperature specific heat data show deviation from the T ...

Although iron is an essential mineral in the homeostasis and functioning of multiple organ systems, its use as a therapeutic entity should be reserved for people with bona fide irondeficiency anemia. Especially when it is added onto preexisting polypharmacy in older adults, iron can subject patients to a plethora of dose-related side effects and drug interactions. Judicious use of laboratory st...

The passage of water through certain bituminous coal mines results in a solution which is extremely acid in reaction because of its high content of ferrous sulfate, some aluminum sulfate, and lesser amounts of manganese sulfate. The ferrous iron is subsequently rapidly oxidized to the ferric state by an autotrophic bacterium. Autotrophic bacteria have also been implicated in the formation of th...
