Investigations on the ferrous sulphate and the ferrous sulphate-cupric sulphate dosimeters

Microbiological Oxidation of the Waste Ferrous Sulphate

Ferrous sulphate, a waste product in titanium white production at the Chemical Plant "Police" S.A., was subjected to microbiological oxidation with Thiobacillus ferrooxidans bacteria. The kinetic parameters of the culture growth were calculated on the basis of the Monod equation. The process was found to be best described by the model of the autocatalytic 1st order reaction with respect to the ...

Practical aspects of ferrous sulphate dosimetry.

Ferrous Sulphate Oxidation Using Acidithiobacillus FerrooxidansCells Immobilized in Ceramic Beads

The immobilization of Acidithiobacillus ferrooxidans cells on ceramic beads as carrier is described. The effects of ferrous ion concentration and dilution on the kinetics of ferrous ion oxidation in a packed-bed bioreactor were studied. In a medium containing 13.91 g of ferrous ion per litre, the fastest oxidation rate was 4.21 g L–1 at a dilution rate of 0.8 h–1. The corresponding conversion w...

Iron deficiency up-regulates iron absorption from ferrous sulphate but not ferric pyrophosphate and consequently food fortification with ferrous sulphate has relatively greater efficacy in iron-deficient individuals.

Fe absorption from water-soluble forms of Fe is inversely proportional to Fe status in humans. Whether this is true for poorly soluble Fe compounds is uncertain. Our objectives were therefore (1) to compare the up-regulation of Fe absorption at low Fe status from ferrous sulphate (FS) and ferric pyrophosphate (FPP) and (2) to compare the efficacy of FS with FPP in a fortification trial to incre...

Oral lactoferrin versus ferrous sulphate and ferrous fumerate for the treatment of iron deficiency anemia during pregnancy

A prospective, randomized, parallel-group, multi-center study was conducted in the Department of Obstetrics and Gynecology at Menoufia University Hospital and central hospitals at Menoufia governorate, Egypt including 300 pregnant women in the second trimester diagnosed with iron deficiency anemia (IDA) who were divided into three groups, the first received lactoferrin capsules, the second rece...
