This research project is designed to study the feasibility of removing or remediating nitrate/atrazine in groundwater using iron powder treatment. Iron powder was selected because it is cheap and nontoxic. Three different types of iron powders were used in this research. They were lab grade iron powder (about 0.02 micron in size), industrial grade iron powder (about 0.5 micron in size), and rus...

The insolubilization of cadmium in the soil of a naturally cadmium-contaminated paddy field was studied using an atomized iron powder and an extracting reagent. Cadmium in the soil was extracted into the water phase by calcium chloride. The extracted cadmium was deposited on the iron powder. The deposition of cadmium was significantly influenced by calcium chloride, since the surface area of th...

nanostructured iron oxide powder that has been recovered from waste pickling liquor unit of steel industry was studied for oxidation catalytic applications. in this research, the powder was characterized by x-ray diffraction (xrd) and transition electron microscopy (tem) for determination of phase structure, morphology and particle size. furthermore, the specific surface area of the powder was ...

In this present work effect of temperature and graphite contents on the microstructural and mechanical properties of iron based powder metallurgy freeform was studied. The different graphite contents (0%, 2%, 5% and 10%) were mixed in iron powder and compact them in 100 KN. These specimens were sintered at 7000 C, 8500 C and 10000 C in muffle furnaces. Microstructural properties were evaluated ...

in this research, the effects of oxygen injection during the induration process were studied in order to improve the quality specifications and increase the rate of production of the iron oxide pellets. several experiments were carried out in palletizing pilot plant in different conditions of oxygen injection. the results suggested that if only the extra oxygen was injected into the furnace in ...

To the Editor, Pica refers to an abnormal appetite for non-edible substances usually occurring in children with developmental disability or brain injury. However, it can also occur during adulthood, as it is associated with iron deficiency. Pica requires medical attention in case of severe eating behaviour that can be potentially harmful. Here we present a case of craving for Johnson's ® baby t...

The effects of powder particle size on the densification and microstructure of iron powder in the direct laser sintering process were investigated. Iron powders with particle sizes ranging from 10 to 200 m were used. It was found that the sintered density increases as the laser energy input is increased. There is, however, a saturation level at which higher density cannot be obtained even at ve...

Abstraet--Ultrafine iron powder was synthesized in an atmospheric-pressure radio-frequency plasma reactor by injecting relatively course iron powder into the plasma, where it evaporated. The renucleated iron particles were characterized by means of a sampling capillary and dilution system interfaced to an electrical aerosol analyzer, a condensation nucleus counter and an electrostatic aerosol s...

BACKGROUND Iron deficiency is a major cause of anemia and the most prevalent nutrient deficiency among pregnant women in developing countries. The use of iron and folic acid supplements to treat and prevent iron-deficiency anemia has limited effectiveness, mainly due to poor adherence. Home fortification with a micronutrient powder for pregnant women may be an effective and acceptable alternati...
