This paper describes the preparation and mechanical properties of an extensive series of very pure alloys of electrolytic iron, carbon, and manganese whose compositions were so chosen as to bring out the specific effects on pure iron of additions of manganese, additions of carbon, and additions of carbon and manganese together in varying relative proportions. The maximum content each of carbon ...

A simple, sensitive, and convenient spectrophotometric method for the determination of diclofenac sodium and piroxicam in pure form and in pharmaceutical formulations was developed. The method is based on the oxidation of diclofenac sodium or piroxicam by iron(III) in the presence of o-phenanthroline. The formation of tris(o-phenanthroline) iron(II) complex (ferroin) upon the reaction of diclof...

Red cells, derived from 13 patients with iron-deficiency anaemia, were found to have a normal life span in the patients' own circulations and those of normal volunteers.

This work reports a study on the heterogeneous Fenton reaction using hematite powder (Fe2O3) in suspension for the discolouration of the reactive dye Drimarene Red X-6BN in aqueous solutions. The efficiency of the process was studied as a function of the experimental conditions: initial pH; H2O2 dose; and hematite powder concentration; all of which showed a strong effect on the reaction kinetic...

indium is a heavy metal belonging to group iiia. it is believed that indium may interfere with iron metabolism from the sites of absorption, transportation, utilization and storage in the cells. the present investigation was established to study and compare the binding of iron and indium to human apo-transferrin (apo-tf). pure human apo-tf was used and the binding activity of iron and indium, a...

The transport characteristics of iron nanoparticles prepared with a green tea, polyphenol-rich solution, were investigated for two granular media, pure silica sand and sand coated with aluminium hydroxide. The GT-nZVI injection caused a sharp decrease in the effluent pH and increase in the redox potential, which is attributed to the presence of free Fe and polyphenols in the suspension, respect...

BACKGROUND & OBJECTIVES The prevalence of anaemia has been well studied particularly on etiology of nutritional anaemia in children of age group 5-10.9 yr in India. The present study was carried out to find out the prevalence and etiology of nutritional anaemia among 5 to 10.9 yr old corporation school children from urban slums. METHODS Urban Delhi slums were divided into four areas and one c...

Earth-abundant iron pyrite (FeS2) shows great potential as a light absorber for solar cells and photodetectors due to their high absorption coefficient (>10(5) cm(-1)). In this paper, high-quality phase-pure and single crystalline pyrite nanocrystals were synthesized via facile, low-cost, and environment friendly hydrothermal method. The molar ratio of sulphur to iron and the reaction time play...
