electrochemically generated iron can remove most contaminants present in water and wast water, by precipitation, adsorption, electrostatic interaction, and complex formation (generally called electrocoagulation-ec). in the present paper, pretreatment of brackish water having high total hardness (th), alkalinity (a),  and cl¯ ions, is studied by application of a dc-electrical current ot the iron...

Hemoglobin and ferritin iron content have been followed during differentiation in tissue cultures of murine erythroleukemia cells (MELC) using the techniques of Mössbauer spectroscopy and electron microscopy. In undifferentiated cells grown without DMSO, only iron stored in ferritin was detected. The amount of iron in a cell grown in the presence of iron citrate is approximately 1.2 X 10(-14) g...

BACKGROUND Two new parameters low hemoglobin density (LHD) and microcytic anemia factor (Maf) have been used by Beckman-Coulter LH series analyzers as an easy screening tool for the early detection of iron deficiency. The main objective of this study was to assess if LHD and Maf could be used for assessment of iron status in blood donors and also to establish a cut-off for these two parameters ...

Honeybees (Apis mellifera) undergo iron biomineralization, providing the basis for magnetoreception. We showed earlier the presence of superparamagnetic magnetite in iron granules formed in honeybees, and subscribed to the notion that external magnetic fields may cause expansion or contraction of the superparamagnetic particles in an orientation-specific manner, relaying the signal via cytoskel...

There is a need for alternative catalysts for oxygen reduction in the cathodic compartment of a microbial fuel cell (MFC). In this study, we show that a bipolar membrane combined with ferric iron reduction on a graphite electrode is an efficient cathode system in MFCs. A flat plate MFC with graphite felt electrodes, a volume of 1.2 L and a projected surface area of 290 cm2 was operated in conti...
