The haemolytic activity of iron-dextran complex is found to be a function of time, temperature, pH, and concentration. The lytic action is enhanced by small amounts of added ferrous sulphate. The lytic action is inhibited by chelating agents such as citrate and sequestrene salts, which bind ionic iron, but not by ferric citrate or ferric sequestrene which do not bind iron. The ionised iron cont...

Thirteen patients with chronic renal failure maintained on regular renal dialysis were studied. Seven proved to have iron deficiency on the basis of marrow iron studies, reticulocyte iron uptake, and saturation of the serum iron-binding capacity. They absorbed iron when given it by mouth and were able to utilize it for haemoglobin formation. Iron-deficient patients given 600 mg of ferrous sulph...

In this paper, we have proposed a simple method to covalently conjugate biotin to magnetic nanoparticles, which can be targeted to the tumour sites by using pretargeting approach with avidin or streptavidin. Magnetic nanoparticles of manganese ferrite were synthesized by alkaline coprecipitation of ferric chloride hexahydrate, ferrous sulphate heptahydrate and manganese sulphate monohydrate usi...

Abstract Limitations of the operation down-flow sand filters were investigated without and with dosages methanol, ethanol, or acetate for denitrification ferrous sulphate to remove phosphorous. The dynamic head loss was developed due clogging by suspended solids (SS) that originated from secondary sedimentation tanks including sludge overflow SS in primary settled wastewater bypassed biological...

In-situ remediation of the Cr(VI) contaminated clayey soil remains challenging due to low hydraulic conductivity and high ion adsorption capacity clays. In this study, injection tests ferrous sulphate (FeSO4) for a with hexavalent chromium (Cr(VI)) were performed explore feasibility FeSO4 solution under different pressures. The results show that pressure 30 kPa, 70 100 kPa caused conductivities...

This study was focused on the historical evolution of waste management policy carried out by Spanish industry devoted to titanium dioxide pigments manufacturing for minimising its environmental impact. challenge achieved modifying original chemical process and converting originally dissolved sulphate sulphuric acid present in final streams factory into minerals (melanterite FeSO4·7H2O, szomolno...

Antianemic medicament ferrous gluconate, ferrous fumarate, and a Dynabi tablet with a basic iron bearing ingredient were studied with the use of Mössbauer spectroscopy. Room temperature spectra of ferrous gluconate gave clear evidence that the two phases of iron were present: ferrous (Fe2+) as a major one with a contribution at and above 91 a.u.% and ferric (Fe3+) whose contribution was found t...
