Non-heme iron as ferrous sulfate does not interact with heme iron absorption in humans
(2012)
The absorption of heme iron has been described as distinctly different from that of non-heme iron. Moreover, whether heme and non-heme iron compete for absorption has not been well established. Our objective was to investigate ...
Effect of Zinc Sulfate Fortificant on Iron Absorption from Low Extraction Wheat Flour Co-Fortified with Ferrous Sulfate
(Springer Science+Business Media New York, 2013)
The co-fortification of wheat flour with iron (Fe)
and zinc (Zn) is a strategy used to prevent these deficiencies
in the population. Given that Zn could interact negatively
with Fe, the objective was to assess the effect ...
Activation of bacteria in agglomerated ores by changing the composition of the leaching solution
(ELSEVIER, 2003-10)
This work presents preliminary results of a study to determine the technical feasibility of heap bioleaching of copper sulfides in a mixed ore that had previously undergone a chemical leach to recover the copper from the ...
Effect of Helicobacter pylori infection on iron absorption in asymptomatic adults consuming wheat flour fortified with iron and zinc
(2011)
Helicobacter pylori infection could impair iron absorption from fortified products. The objective of the study was to determine the effect of H. pylori infection on iron absorption from asymptomatic adults consuming wheat ...
Copper Electrodeposition Kinetics Measured by Alternating Current Voltammetry and the Role of Ferrous Species
(Electrochemical Soc, 2016)
Impurities and additives play a key role in copper electrodeposition, in particular in upstream processes such as electrowinning or electrorefining. One common impurity is iron, mostly present as iron species Fe(II) in ...
Temperature dependence of the cathodic and anodic kinetics in a copper electrowinning cell based on reactive electrodialysis
(PERGAMON-ELSEVIER SCIENCE LTD, 2005-09)
The temperature dependence of various kinetic parameters for the copper electrodeposition reaction and for the ferrous to ferric ion oxidation has been experimentally determined. Potentiodynamic sweeps were carried out in ...
Prevención de anemia en prematuros: transfusiones con eritropoyetina. Hospital de San José, 2006-2008
(Sociedad de Cirugía de Bogotá, Hospital de San José y Fundación Universitaria de Ciencias de la Salud, 2009-06-01)
Preparation and characterization of iron-alginate beads with some types of iron used in supplementation and fortification strategies
(Elsevier, 2018)
Our work aimed to develop and characterize different alginate beads with either non-heme iron or a blend of heme/non-heme iron. We chose non-heme iron salts such as ferrous sulfate (FS), ferrous ammonium sulfate (FAS), ...
Speciation of the Fe(II)-Fe(III)-H2SO4-H2O system at 25 and 50 degrees C
(ELSEVIER SCIENCE BV, 2005-12-30)
This work presents theoretical and experimental results on the speciation of the Fe(Il)-Fe(III)-H2SO4-H2O system in concentrated solutions (up to 2.2 m H2SO4 and 1.3 m Fe). The aim was to study the chemical equilibria of ...
Absorption of Iron from Ferritin Is Independent of Heme Iron and Ferrous Salts in Women and Rat Intestinal Segments
(AMER SOC NUTRITION, 2012-03)
Ferritin iron from food is readily bioavailable to humans and has the potential for treating iron deficiency. Whether ferritin iron absorption is mechanistically different from iron absorption from small iron complexes/salts ...
